40' x 90' Classic Frame Aluminum Double Tube 7' Pole and Fitting Kit

40' x 90' Classic Frame Aluminum Double Tube 7' Pole and Fitting Kit

The 40' x 90' Classic Frame Aluminum Double Tube 7' Pole and Fitting Kit is a heavy-duty structural framework designed to support expansive temporary shelters for large-scale events. Engineered specifically for the needs of a high-volume event rental company, this kit provides the skeleton for a massive 3,600-square-foot footprint. By utilizing structural-grade aluminum double tube construction, the frame offers significantly higher rigidity and torque resistance than standard single-tube systems. This increased strength is essential for maintaining the integrity of such a long-span tent installation, ensuring that the structure remains stable and secure during major festivals, weddings, or corporate assemblies.

This kit is a comprehensive hardware solution, including all the 7-foot leg poles, rafters, spreaders, and heavy-duty steel fittings required to assemble a complete West Coast Style frame. Because it follows industry-standard design principles, these components are fully interchangeable with other West Coast Style inventories, allowing for simplified maintenance and fleet management. Whether you are building a new structure from the ground up or replacing an aging framework, the double tube system provides a professional, high-strength foundation that can withstand the tension of large vinyl tops and the demands of frequent outdoor use.

Why the 40' x 90' Double Tube System Matters

As tent lengths reach 90 feet, the structural load on the framework increases exponentially. The 40' x 90' Classic Frame Aluminum Double Tube 7' Pole and Fitting Kit addresses this by using reinforced aluminum tubing with a double-channel profile. This design prevents the bowing and flex often seen in single-tube frames of this size, providing a safer and more professional event setup. For the installer, this means a more reliable structure that stays square and plumb, even under high wind loads or heavy tension. Investing in a double tube system ensures your equipment has a longer service life and provides a superior level of safety for guests and clients.

Key Features

• Reinforced Double Tube Aluminum: Engineered with a double-channel profile for maximum structural stiffness across wide 40-foot spans.
• 7-Foot Eave Height: Traditional leg height provides a comfortable perimeter and ease of entry for high-traffic events.
• West Coast Style Compatibility: Fully interchangeable with standard West Coast Style poles, fittings, and tent tops.
• Heavy-Duty Welded Steel Fittings: Includes all necessary crowns, side tees, and corners manufactured from zinc-plated steel for maximum durability.
• Massive 3,600 Sq. Ft. Capacity: An expansive footprint designed for large-scale seating, staging, and banquet layouts.
• Corrosion-Resistant Materials: Anodized aluminum and plated steel components are built to withstand moisture and repeated outdoor use.
• Modular Sectional Design: Engineered 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 90' framework, a systematic approach and an experienced crew are required for a safe and efficient installation.

Step 1: Inventory and Site Layout

Clear the site of debris and lay out all poles and fittings on a protective drop cloth. Organize components by color-coded lengths (rafters, spreaders, and legs) to ensure a smooth assembly process and prevent confusion during the tent installation.

Step 2: Assemble the Roof Framework

Begin by connecting the ridge crowns to the rafters and double tube spreaders. Work your way out from the center to the perimeter. For a 40' x 90' frame, verify that all internal support cables are properly tensioned and that every fitting is secured with R-pins or pin-and-bail fasteners to prevent components from shifting.

Step 3: Fabric Application

Before raising the frame on its legs, pull the vinyl tent top over the roof structure. Secure the top to the perimeter spreaders. Managing the fabric at ground level is much safer and more efficient than trying to adjust it once the 90-foot long tent is at full height.

Step 4: Raising the Structure

With a crew of 8 to 12 people, lift one side of the frame and insert the 7-foot leg poles into the fittings. Once the first side is stable, repeat the process for the opposite side. Ensure all legs are seated properly in the base plates and the frame is level.

Step 5: Anchoring and Tensioning

A structure of this magnitude requires robust anchoring at every leg location. 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.
