Glossary of Tent Terminology

A - J

An optional item or add-on not required for installation. Examples include sidewalls, lighting, flooring, flags, etc.


Alligator Clip
Also known as thumb buckles, alligator clips are a tension device used to tighten perimeter webbing straps on Classic Series Frame Tent systems.


Method of securing a tent, canopy, shelter, or structure to the ground. Examples include stakes, concrete anchors, deadweights, or water barrels.


Anodized Aluminum
Aluminum that is treated so that it forms a hard, protective coating to improving outdoor performance. Components, tubing, and poles are made from anodized aluminum.


Anti-Sink Plate
A wood or steel plate that is positioned on the ground under a pole to displace the downward force of center poles and side poles. Commonly used on pole tents and tension tents to reduce the risk of poles sinking into the installation surface.


The amount of ground surface under the tent, canopy, structure, or shelter. Additional space for stakes, anchors, and guy lines outside of the tent's "area" is required. See Footprint.

A sheet of fabric material designed to hang from the eave of the tent, creating a rear wall. Common backdrops are printed for advertising purposes.


Blockout Fabric
Blockout or blackout fabric is opaque, not allowing light to pass through (the opposite of a translucent fabric). Interior lighting may be required when a tent or shelter is fully enclosed with sidewalls made out of blockout fabric. Blockout fabrics are recommended for all tents, canopies, shelters, and fabric structures.

Box Ratchet
A mechanical tension device used with guy lines to secure a tent, canopy, shelter, or structure to the ground. Similar to a ratchet buckle assembly, box ratchets replace old-fashioned rope tie-down anchoring methods.


This is the name gives to each different style of tent. Also see series.

A small, light-duty tent, usually without sidewalls. Canopies typically have one-piece tops, and aren't expandable. Designed for shade against the sun or light rain.


Center Pole
The pole that supports the tent fabric, located at the center of the tent. Center mast poles run vertically from the ground to the peak of the tent and require interior floor space. For ease of handling and transportation, center poles generally telescope or disassemble into 2 or 3 pieces.


The type of structure or framework that supports the fabric. CELINA tents, canopies, marquees, shelters, and fabric structures can be classified into 6 categories:


Cross Cable

Rigid framework perimeter, utilizing steel cables to support a center pole or ‘flying mast’ (no center poles or obstructions that touch the ground in the center of the tent). Also known as a “frame & cable” tent.

Series/Brand: Pinnacle Series Hexagon High Peak Frame Tents, Pinnacle Series High Peak Frame Tents

Pop Up

Accordion-style, complete-intact internal framework supporting the fabric (no center poles or obstructions).


Series/Brand: Athens Utility Shelter, Fast Shade Pop Up Canopy, Pronto Pop Up Canopy


Freestanding or internal framework that supports the fabric (no center poles or obstructions).


Series/Brand: Classic Series Frame Tents, Master Series Frame Tents, Master Series High Peak Frame Tents, Classic Series Gable Frame Tents, HGPTS (Humanitarian General Purpose Tent System)


Extruded channeled beams with sliding fabric panels form a complete framework (no center poles or obstructions).


Series/Brand: PROspan Fabric Structures


Internal center poles and perimeter side poles supporting the fabric. Requires stakes and/or anchors around the perimeter to create the proper tension (center poles require interior floor space).


Series/Brand: Classic Series Pole Tents, Presto Series Pole Canopies, Premiere I Series High Peak Pole Tents, Premiere II Series Engineered High Peak Pole Tents, TP Series Tents

Truss Arch

Rigid internal arch-shaped truss framework that supports the shelter fabric (no center poles or obstructions).


Series/Brand: Crestline Truss Arch Fabric Structures

Cold Crack
Cracking or fracturing caused by long exposure to extreme cold. When vinyl reaches the temperature where it loses its pliability, flexing the PVC film can cause the vinyl to flake off and expose the scrim. To reduce the effects of cold crack, tension the fabric evenly to eliminate unnecessary movement. Cold Crack should not be confused with wind whip, even though the damage to the fabric looks similar.


Complete Tent
A tent that has all of the necessary components to be fully installed per CELINA's recommendation, as listed in the tent's product manual. A complete tent does not include sidewalls. For more information, see Accessory or Component.


An individual item required for proper installation. Examples include side poles, frame fittings, tent anchors, or fabric mid-sections. For non-essential items see Accessory.


Custom Printing
Most fabric products can be custom printed with graphics such as text, logos, or images. Printing is integrated into CELINA's manufacturing process and is therefore not a stock item. Production lead times range from 4 days to 3 weeks after customer artwork is approved.

Digital Printing
The full color printing process used to custom print fabric products such as tent tops, sidewalls, and banners.


Drop Cloth
Also called a ground tarp; a protective sheet of fabric used to reduce damage to the tent top fabric and keep it clean during installation and removal. Drop cloths reduce the risk of pin holes, scuffs, and abrasions which can lead to scrim mold.

Dye Sublimation Printing
Full Color Printing Process which incorporates heat to set the ink into the polyester based fabric materials. Dye sublimated fabric products include tent/canopy tops, sidewalls, backdrops, table covers/throws, carpeting, and flags.

Ease of Setup
Complexity of installing a tent, canopy, or shelter system. Variables such as tools, equipment, installation site terrain, experience, weather, and the amount of installers available will greatly impact the Ease of Setup.


The location where the valance meets the fabric roof. For frame tents, the eave is the perimeter spreader tubing location. On a pole tent, the eave is at the top of the side pole.


Eave Height
The vertical dimension from the ground to the top of the valance. Eave heights are determined by the length/height of the side pole or leg. Eave and peak heights directly correlate; if the eave height changes, the peak height must change by the same amount. The pole pin is not included in the eave height measurement. Eave heights will vary between tent styles and brands.


ECU Duct
Environment Control Unit. Duct openings to receive HVAC supply and return air. This is a standard option on tactical and humanitarian shelter systems.


EFT Duct
Electrical Feed Through. Duct opening(s) to receive electrical and communication lines. This is a standard option on tactical and humanitarian shelter systems.


End Section
Also End; the portion of an expandable tent's fabric that only has lace or grommet connectors on one side (denoting a lace end or grommet end). The plural term 'Ends' is used to describe a pair consisting of 1 grommet end and 1 lace end.


Engineered Tent
Tents engineered to meet the requirements ASCE 7-05, IBC 2006, and/or IFC 2006 and withstand 90 mph, 3 second wind gust, exposure "C" including dead load, pre-stress, and 3 pounds per square foot (psf) uniform gravity load. Engineered tents are suited for very sizes and/or long-term installations. Please note that the engineered tent design is rated and stamped by a professional engineer, but the engineering stops at the staking or anchoring locations. This means it is the end user's or installer's responsibility to ensure proper staking methods are used for the appropriate soil conditions.


The ability of a tent or shelter system to be lengthened or shortened by adding or removing fabric sections and hardware components. Expandable tent or shelter systems can be built to any desirable length. Fabric sections are joined together using methods such as grommet & lace lines or Keder track.



Small metal reinforcement rings and holes inserted into fabric, used mainly in small fabric banners and for grommet lines in sectional tent tops. Also referred to as a grommet.

The predominate material used to construct the covering portion of a tent, canopy, structure, or shelter. Commonly used fabric materials are PVC Coated Polyester/Vinyl and Polyester.


The hardware connector that joins tubing to create a frame tent's framework. Also known as a frame tent fitting, connectors, and spiders.


Flame Certificate
Documentation that states that the material used to manufacture a tent, canopy, shelter, fabric structure, sidewall, or fabric accessory is nonflammable or flame resistant. Flame Resistant Certificates may be required by local fire and/or building inspectors prior to installation. Visit our Flame Resistance Certificates page for more information.


Flame Resistant
Flame resistant means nonflammable; it does NOT mean fire proof. The fabric will burn if left in continuous contact with an open flame. Open flames should never be used under any tent, canopy, structure, or shelter. CELINA fabrics are inherently flame resistant or meet or exceed one or more of the following flammability specifications:

  • NFPA-701
  • CPAI-84
  • ASTM D 6413
  • BS 5438
  • BS 7837 (1996)
  • DIN 4102-B1

A 3-piece metal component used to secure fabric sections together at the center pole location(s). Created by connecting 2 floor flanges with a pipe nipple, the device allows for easy installation of pole pins during installation.


The total space required for finished installation of a tent, canopy, structure, or shelter. This is including stake locations, anchors, and guy lines. Additional space may be required for layout and setup. See area.


Frame/Pole Material
The material used to create the tent's support structure. Frame tents are constructed using 'tubes' or 'tubing,' while pole tents are assembled with 'poles'. Example material types: anodized aluminum, galvanized steel, and fiberglass reinforced pipe (FRP).


Frame Fasteners
The components used to secure a frame tent fitting to frame tubing. Fastener Types consist of r-pins, pin and bails, and bolts/nuts.

Frame Tent
A tent with an assembled framework made of aluminum or steel tubing that supports the fabric roof and defines the shape of the structure.

Galvanized Steel
Steel components, poles, or tubing that has a protective coating of zinc to prevent rusting. Steel, even galvanized steel, is prone to rust, and therefore items should be covered when not in use to prevent or minimize rust formation.


Gang Staking
The method of connecting multiple stakes with stake plates to create one anchoring point. Also known as cluster staking. Also see stake plates.

General Purpose Shelters
Shelters specifically created to be used in any situation, from standard installations to relief efforts. See humanitarian tent.


A reinforcement ring and hole inserted through the fabric material. They are used to prevent tearing or damage to the material. Grommets are used on sidewalls, pole tents (at all pole locations), and on grommet lines used to lace sectional tents together. A small grommet may also be referred to as an eyelet.


Grommet End
Fabric piece of a sectional tent containing a line of grommets or eyelets, that when combined with other units create a sectional tent top. Grommet lines mate with lace loops.


Guy Line
The rope or ratchet buckle assembly that connects the fabric or frame system to a ground anchor, stake, or weight. Guy lines and anchors are set out from the perimeter of the tent, canopy, structure, or shelter, adding to the tent area. See footprint or area.

The line on the tent roof running from a corner eave location to the peak or center pole location.


Hip Rafter
The piece of frame tubing that runs from the corner eave fitting to the peak/crown fitting.

Humanitarian Tent
Humanitarian or disaster relief tents are non-tactical shelters designed to offer an economical solution for humanitarian aid in the event of a natural disaster or conflict. General purposes include medical facilities, billeting, field services, and storage. Also see general purpose shelters.

Individuals Required for Setup
Recommended minimum number of people required to install the system. Installation and safety equipment is recommended where applicable. Variables such as tools, equipment, installation site terrain, and weather will greatly impact the number of Individuals Required for Setup.

Jump Rope
A rope attached to the tent top fabric at all pole locations, used to keep the fabric from lifting of "jumping" off of the pole pin. Jump ropes are wrapped around the pole and tied after the tent top has been installed.

K - T

A flexible cord wrapped in a woven polyester fabric, attached to the edges of fabric panels. This allows the panels to be pulled through and secured in tubing or poles with an aluminum extrusion, creating a seam to join multiple fabric sections together. Keder is an alternative to the traditional lace line, and can be used on sidewalls as well as fabric tops.


Keder Tubing
Lengths of Anodized Aluminum extruded to form channels or 'keder track' which receives fabric panels finished with keder.

Lace End
Fabric piece of a sectional tent that contains lace loops, which combined with other units to create a sectional tent top. Lace loops are fed through the grommets/eyelets in grommet lines to create a secure connection.


Lace Line
The connection that is used to combine pieces of a sectional tent. A lace line is formed by combing two parts, the grommet section on one piece and the lace section on another.

The measurement of the tent, canopy, structure, or shelter from end to end. This is the 'long side' of the tent, or the side of a sectional tent that is expandable to any desired length. When looking at the name of a tent from Celina Tent, this is the second number listed. For example: a 20' by 40' Classic Series Frame Tent has a 40' length.


Longest Component
The longest tube/pole required to install the tent, canopy, structure, or shelter. The length value will help determine the size of truck or trailer that is required to transport the complete system.

Another name for "tent." Specifically, a long and narrow tent without sides used for sheltering walkways or defining an entry to a tent, building, or house.


A vinyl coated polyester scrim that is breathable, lightweight, and strong. A remarkably versatile fabric, typical screened mesh uses include printed sidewalls, windscreens, gym divider curtains, banners, fencing, and standard tent sidewalls.


Mid/Middle Section
A sectional tent top's fabric portion that contains both lace loops and eyelet/grommet lines on opposite edges. Mid sections are combined with lace and grommet ends to create a sectional tent, and can be added to a sectional tent to expand it to any imaginable length.


Mold and Mildew Resistant
The ability of the fabric to resist mold and mildew growth on its surface. Regardless of resistance, precautions must be taken with all tent fabrics to store them clean and dry to discourage mildew growth. For internal mold and mildew, see scrim mold.

National Stock Number (or NATO Stock Number), a 13 digit numeric coded identifying the 'standardized material items of supply' for the US Department of Defense and other NATO countries. CELINA manufactures numerous fabric products that are stock-listed and have NSNs. Example NSN: 8340-01-535-6379.

Occupancy/Seating Capacity
The number of people who can occupy or be seated under a tent, canopy, structure, or shelter. The seating capacity will vary by seating arrangement, such as buffet dinner, sit down dinner, or cathedral/row seating, in addition to any tables that may be set up as well. Click here to view our Occupancy & Seating Page.


One Piece Tent Top
The fabric portion of a tent manufactured to the entire tent area size. The tent or canopy top cannot be expanded or reduced in length.

Does not allow light to pass; the opposite of translucent. Standard PVC fabric is opaque. See also Blockout Fabric.


Overall Height
The distance between the base and the highest exterior point of a fully installed tent. For pole tents, the pole pin is included in the Overall Height measurement.

PAR Lighting
Parabolic Aluminized Reflector light; directional lighting instrument whose beam spreads from a very narrow spot to a wide flood. PAR lights are commonly used for commercial, event, and hospitality applications.


Peak Height
The very highest vertical point of the fabric from the ground. The Peak Height may also be defined as the ridge height or apex. Peak and eave heights must be in direct correlation; if the eave height changes, the peak height changes by the same amount. For pole tents, the pole pin is not included in the peak height measurement.


Pin Hole
A small puncture or hole that penetrates through single or multiple PVC layers. Pin holes may cause fabric discoloration due to scrim mold, or allow excess light to pass through the blockout fabric which creates the appearance of 'stars in the night sky'. Pin holes can be repaired using Pin Hole Patch by CELINA; left uncovered, pin holes can contribute to scrim mold.


Pitch/Roof Pitch
The degree of slope in the tent roof, measuring the vertical distance between the tent eave and the peak height of the tent roof. This term differs from the term 'pitch' used in the construction and building industries. The pitch of a tent, canopy, or shelter can be calculated by subtracting the eave height from the peak height.


Pole Pin
The rod attached to the top of a side pole, center pole, and quarter pole that is inserted through the grommet on pole tent tops.


Pole Tent/Push Pole Tent
A tent with a set of individual poles arranged beneath the fabric roof to support and define the shape of the structure. The fabric roof is stretched over the poles and attached to ropes and/or webbing at leg/side pole locations around the fabric's edge. The ropes or webbing are pulled tight, securing to the ground using stakes, anchors, or augers around the perimeter of the tent.


The structural member used to support the fabric of a pole tent or tension tent. There are 3 standard types of poles: side poles, center poles, and quarter poles. Poles are not used for frame tents.


The standard woven fabric used to construct smaller tents, canopies, table covers, backdrops, and flags that are printed using a high definition dye sublimation process. All woven polyester fabrics from Celina Tent meets fire ratings, so are approved for interior and outdoor applications.


PVC Coated Polyester
The standard fabric used to construct tents, shelters, canopies, and structures. PVC laminated materials are available in 10oz, 14oz, 16oz and 18oz weights. All PVC coated polyester from CELINA meets fire ratings, so are approved for interior and outdoor applications. CELINA's PVC fabrics are also made using mildew resistant and UV blocking additives. See also blockout fabric, vinyl.

Quarter Pole
The upright post that supports a tension tent top, located halfway between the side pole(s) and the center pole(s). Two quarter poles combined with one center pole divides the tent top into quarters. Quarter poles are used on 60' wide and 80' wide Classic Series Pole Tents.


Quonset Hut
A pre-fabricated structure that has a semi-circular cross section. CELINA's Truss Arch Fabric Shelter is a quonset hut, with additional designs for straight-walled versions.

Frame tent tubing that runs from a side tee (eave) fitting to the peak/crown fitting.

Rail Skirt/Rail Curtain
A divider or half-wall used to create a partition or railing for exhibit booths, trade shows, gaming booths, etc. They are attached to the tent legs with additional hardware and are often custom printed with branding or advertising.


Ratchet Buckle Assembly
Mechanical tension device used in guy lines to secure a tent, canopy, shelter, or structure to the ground. Operated by hand, ratchet buckle assemblies replace old fashioned rope tie downs. A complete ratchet buckle assembly includes a ratchet buckle strap and a loop strap, made out of webbing and ratchet buckle hardware.


A product image that incorporates the customer's graphic or photo, demonstrating what a custom printed product will look like after production. Renderings are generated by Celina's customer service team and approved by the customer prior to the start of custom printed product production.

Coarse woven polyester threads used for reinforcement in both laminated PVC vinyl and coated PVC vinyl. The flexible scrim material is encapsulated in PVC using either a lamination or coating process to create the fabric. Scrim adds the tensile strength to the PVC material.


Scrim Mold
Mold or mildew which grows inside the canopy fabric. This occurs when moisture penetrates the scrim through small abrasions and/or pin holes in the laminated or coated PVC film layer. Scrim mold will cause discoloration to the vinyl, and cause dark areas in translucent fabric as light passes through. There is no way to remove scrim mold or its effects once it has occurred. Scrim mold is visible through translucent fabrics, but not visible through blockout fabrics.


Sectional Tent Top
The fabric portion of a tent consisting of two or more fabric units that are combined at lace lines to create a single tent top. Sectional tent tops are expandable and can be lengthened to any desired length by adding mid sections. A standard sectional tent top consists of two ends and a mid-section.

The identity assigned to a tent, canopy, structure, or shelter and used to identify the unique characteristics between sizes, styles, and class types. Also see brand. Brands are as follows:

Sewn Seam
The joint where two or more layers of fabric, webbing, or other materials are held together with stitches. Standard stitches are created with a polyester thread. This creates a strong, mechanical bond; however, the stitching can create an area for moisture to penetrate waterproof fabrics, in which case welded seams are preferred.


The common term used by the military and other government agencies to describe a tent or structure repurposed to meet specific long term mission needs. Examples uses are disaster relief, billeting/lodging, work tents, logistics/warehousing/storage, etc.


Side Pole
Upright poles that support the eave of a pole tent. Side poles are used in conjunction with ratchets/ropes to create tension across the fabric and hold the tent aloft.


Sidewall Rope
The rope line that runs along the perimeter of a tent or canopy, sealed to the inside, allowing for sidewalls to be attached and enclose the tent.


A removable sheet of fabric designed to hang from the eave around the perimeter of the tent, used to block the interior of the tent from the outdoor elements. Sidewalls are available in various types and may not be interchangeable between tent classes. Also called a tent wall or side curtain, sidewalls can be connected through side release buckles, zippers, or hook & loop to fully enclose the tent.


Site Inspection
Process of reviewing the installation area prior to setup to ensure safety and efficiency. Job site inspections review: location, underground obstructions, overhead obstructions, and surface conditions.


Frame tent tubing that runs horizontal to the ground when installed. A spreader tube will join corners, side tees, and crown fittings, or any combination thereof.


Squaring/Square a Tent
The process of marking the perimeter and stake and anchor locations prior to laying out the tent fabric. This process is also known as a pre-staking.

Stake Line
The arrangement of tent stakes around the perimeter of the tent. This term is often used when pre-staking or squaring a tent. Stake lines may also be referred to as 'guy out points'.


Stake Plate
A flat piece of steel that allows gang staking or cluster staking by connecting multiple stakes, creating one anchoring point. Stake plates are used on large tents and in situations where soil conditions are inadequate for standard staking. Also see gang staking.


Rods, spikes, or pins constructed of steel, wood, or plastic and driven into the ground. Guy lines from the tent are attached to stakes to secure the tent. The most common stakes sizes are 42"x1" and 36"x1" steel stakes.


Also 'Strike Procedure', the process of dismantling, de-installing, removing, and/or tearing-down a canopy, tent, marquee, or structure. The opposite of the setup or installation process.


A type of tent where the assembled frame work of heavy-duty box beams or keder extrusions support the fabric roof and define the structure's shape. Structure may also be referred to as a clear-span or free-span tent.


The geometric form that defines the look of a tent, canopy, structure, or shelter.

The blank file containing product guidelines, form and fit parameters used to create printed products. Used to let customers and the CELINA graphics department lay out designs and artwork on a product.


Temporary Structure
A tent or structure that will be in place for less than 180 consecutive days. The definition may vary according to local building and fire codes.


A temporary structure composed of a covering made of a pliable fabric, supported by poles, metal frames, beams, columns, arches, ropes, or cables. Tents are also referred to as a marquees, canopies, or pavilions.


Tent Package
A complete tent set, containing all fabric and hardware for immediate installation and including optional items such as upgraded pole or frame systems, colored tent fabric, or sidewalls to completely enclose the tent.


Tent Top
The fabric portion of the tent, shelter, canopy, or fabric structure. The top can be a '1 piece tent top' or a 'sectional tent top'. The tent top combined with frame tubing, pole kit, and/or stakes will create a complete tent. Top options can include solid white, color & white or full color digital printing.


Translucent Fabric/Translucency
Translucent fabric allows light to pass through, the opposite of blockout or opaque fabric. A tent constructed of translucent fabric will allow natural light to come through and may reduce the need for interior lighting when daylight is present.

Truss Arch Shelter
A fabric shelter constructed of arched metal beams that support the roof fabric. Truss Arches can be constructed using single arch or double arch designs. Shelter walls can be constructed using vertical or arched designs. Truss arch shelters may also be referred to as hoop buildings or Quonset huts.

The structural member used to construct the frame work of a frame tent. Common tube lengths are interchangeable between tent sizes. Tubing is available in 4 configurations: Aluminum Single Tube (AST), Aluminum Double Tube (ADT), Galvanized Single Tube (GST), and Keder Single Tube (KST) which is commonly used for legs or uprights for a tent.

U - Z

UV Resistant
The ability of the fabric to resist deterioration from ultra violet (UV) light. UV or sunlight will cause non-resistant materials and surfaces to break down and fade or discolor.

The section of fabric material that hangs from the eave of the tent or canopy top. Valance length and style vary between product brands and styles. CELINA's 3 main valance styles are:

Scalloped Valance
Straight Valance
Catenary Curve Valance

The standard fabric used to create tent tops, sidewalls, etc., made from scrim that is coated or laminated with polyvinyl chloride (PVC). Also see PVC coated polyester.

Water Barrels
A drum or container filled with liquid and used as weight to secure a tent system. Water barrels are not a reliable system anchoring any type of tent, canopy, shelter, or structure system and should never to be used. For more information, watch the following videos:

Water Repellent/Water Resistant

The ability for a material to resist liquid soaking into it. Water repellent fabric is designed to shed water, but will soak through and drip in extreme downpours. This fabric is both tightly woven and specially treated with a finish, such as a polyurethane backing. Water will bead on the fabric's surface rather than permeate it. Over time, with UV exposure and washing, the water repellent finish can wear off.



Material that doesn't allow water to penetrate the layers. Waterproof fabric is designed to keep the area under the fabric dry even in the heaviest rains. Usually reinforced PVC, waterproof fabric is extremely tightly woven and nonporous, constructed with tightly sealed or welded seams.



Webbing is a strong fabric woven into a flat strip of varying width, often used in place of rope or as reinforcement on fabric products. Two types of webbing are commonly used:

  • Sewn Webbing: Typically constructed from polyester, this type of webbing is sewn to the fabric or hardware. Sewn stitches create puncture holes in the webbing and fabrics, therefore creating potential leak issues if not water proofed.
  • Weldable or Heat Sealable webbing: Constructed from a woven polyester base and then coated with PVC to allow the webbing to be hot air or high frequency welded to the fabric's surface. Heat sealed webbing eliminates all stitching or puncture holes in the fabrics, therefore preventing moisture intrusion or leakage on waterproof fabrics.

Welded Seam

A thermally sealed fabric seam using hot-air, hot-wedge, or RF (radio frequency) welding processes that form a water tight bond. Also referred to as a heat weld, heat seal, or seal.


West Coast Style Frame
The name of the universal frame tent system CELINA uses for our frame tents. West Coast Style fittings are interchangeable with other traditional frame tents from most major tent manufacturers.

The measurement of the tent, canopy, structure, or shelter from side to side. Generally this is the 'short side' and it is not expandable. When looking at the name of a tent from Celina Tent, this is the first number listed. For example: a 20' by 40' Classic Series Frame Tent has a 20' width.


Wind Whip
Damage caused by lack of tension in the fabric, making it flap in the wind. After time, vinyl-coated fabric will become fatigued and the coating will flake off, exposing the scrim. To reduce the effects of wind whip, tension the fabric evenly to eliminate unnecessary movement. Wind Whip should not be confused with Cold Crack, even though the damage to the fabric looks similar. Below is an example of what a piece of fabric looks like that has been damaged by wind whip.


X is always for xylophone.
