40' x 80' Classic Frame Aluminum Double Tube 7' Pole and Fitting Kit

40' x 80' Classic Frame Aluminum Double Tube 7' Pole and Fitting Kit

The 40' x 80' Classic Frame Aluminum Double Tube 7' Pole and Fitting Kit is an industrial-strength structural solution engineered for the most demanding large-scale events. Providing a massive 3,200 square feet of unobstructed interior space, this kit is the professional choice for a rental company tasked with hosting major wedding receptions, corporate assemblies, or large community festivals. By utilizing heavy-duty aluminum double tube construction, this framework offers superior rigidity across its 40-foot span, ensuring that the structure remains stable and secure even when fully tensioned with a large vinyl top. The 7-foot leg height provides a traditional, accessible perimeter that is ideal for high-occupancy gatherings.

This kit serves as a comprehensive hardware replacement or a foundation for a new West Coast Style frame system. Because it adheres to industry-standard dimensions, the components are fully interchangeable with existing West Coast inventories, allowing for simplified maintenance and fleet management. The double-channel design of the aluminum tubing provides a much higher strength-to-weight ratio than traditional single-tube pipes, making it the safest and most durable option for 80-foot long structures. Whether you are expanding your inventory or performing a critical tent installation for a high-profile client, this double tube kit delivers the professional performance required in the field.

Why the 40' x 80' Double Tube System Matters

In the event industry, the integrity of the frame is the most critical factor in site safety. A structure spanning 80 feet in length faces significant wind loads and fabric tension. The 40' x 80' Classic Frame Aluminum Double Tube 7' Pole and Fitting Kit is designed to mitigate these forces through its reinforced structural profile, which resists the bowing and twisting that can occur in lighter frames. For a professional event setup, this translates to a straighter, cleaner-looking tent that inspires confidence in clients and provides a safer environment for guests. The modular nature of the kit also allows for efficient transport and organized teardown after the event is concluded.

How to Use / Installation Best Practices

Due to the size and weight of a 40' x 80' framework, a systematic approach and a large, experienced crew are required for a safe tent installation.

Step 1: Inventory and Site Layout

Laying out the components correctly is the most important step for a fast event setup. Clear the site and place all rafters, spreaders, and 7-foot legs on a protective drop cloth. Organize by color-coding to ensure the correct lengths are used for the ridge, rafters, and perimeter.

Step 2: Roof Frame Assembly

Assemble the central ridge first, connecting the crowns to the rafters and double tube spreaders. Work your way out to the perimeter. For a 40' x 80' frame, verify that all internal support cables are properly tensioned and that every fitting is secured with R-pins or pin-and-bail fasteners.

Step 3: Vinyl Top Placement

While the frame is still at ground level, pull the vinyl tent top over the roof structure. Centering the top and securing it to the perimeter spreaders at this stage prevents the wind from catching the fabric and makes the lift much safer for the crew.

Step 4: Raising the Frame

With a crew of 8 to 12 people, lift one 80-foot side of the frame simultaneously and insert the 7-foot leg poles into the fittings. Once the first side is locked, repeat the process for the opposite side. Ensure all legs are plumb and the frame is square before proceeding.

Step 5: Critical Anchoring

A structure of this magnitude requires robust anchoring at every leg. Use professional stake driving equipment to secure the base of each leg and attach heavy-duty ratchet straps. Tension the straps evenly to ensure a drum-tight finish and maximum structural stability.
