Product Description

55mm (2.16″) Aluminum Truss Coupler Spacer – Male to Male Coupler Expansion Insert (EVT290A-CS55)

The EVT290A-CS55 is a specialized 2.16-inch (55mm) aluminum coupler spacer designed for 290 mm square conical aluminum truss systems. This unit features a substantial machined central collar that adds exactly **55mm (2.16″)** to the length of the truss span. It replaces a standard coupler to provide a secure, male-to-male structural connection while extending the measurement to fit custom architectural dimensions.

Function & Compatibility:

This unit serves as a direct replacement for a standard connector. It inserts into the female receivers of two adjoining truss segments, providing a male connection on both ends. The integrated 55mm collar creates the necessary spacing between the truss chords while maintaining the rigidity and safety of the conical bond. It is fully F34 Compatible, ensuring seamless integration with EVT290S and most major 290mm conical truss brands.

Key Features

• Precision Adjustment: Adds exactly 2.16 inches (55mm) to the truss connection.
• Compatibility: F34 Compatible design integrates seamlessly with standard 290mm square truss systems.
• Integrated Design: A single-piece male-to-male coupler with a built-in spacer collar.
• Gap Solution: Solves spacing issues where standard lengths fall short.
• Material Type: Precision-machined from high-grade Aluminum Alloy EN AW-6061 T6.
• Durable Construction: Fabricated to withstand the compressive forces of the truss rig.

Designed by Evolve Truss, the EVT290A-CS55 allows riggers to fine-tune truss lengths without relying on loose shims or washers.

⚠️ Safety & Engineering Notice

❗ Critical Load Rating Information:

• Structural Integrity: The EVT290A-CS55 is a structural component. Do not exceed the load capacity of the spacer or the truss system it is modifying.
• Load Placement: No loads are permitted or should be supported directly from the connection point where the spacer is installed.

Important Guidelines for Safe Use:

• Inspect the spacer thoroughly before use; do not use if damaged, deformed, or cracked.
• Ensure all coupler connectors, pins, and cotter pins are installed correctly and fully secured.
• Do not attach truss with damaged or fewer connectors than required.
• The purchase of this product does not authorize specific installations; a licensed professional engineer shall review all structures.

⚠️ Compatibility Warning

Crucial Steps for Safe Assembly:

• Fit Check: Verify that your conical coupler is long enough to fully engage both truss receivers when the spacer is inserted.
• Brand Mixing: While F34 compatible, always test-fit connections with other brands on the ground before lifting.
