Product Description

EVT290A-CS20 | 20mm (0.79″) Male-to-Male Coupler Spacer

The EVT290A-CS20 is a specialized double-ended male conical coupler designed for EVT290S 290 mm square conical aluminum truss systems. Much like the 10mm version, this unit features a larger machined central collar that adds exactly **20mm (0.79″)** 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 & Assembly:

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 20mm collar creates the necessary spacing between the truss chords while maintaining the rigidity and safety of the conical bond.

Key Features

• Integrated Design: A single-piece male-to-male coupler with a built-in spacer collar.
• Precision Adjustment: Adds exactly 0.79 inches (20mm) to the truss connection.
• Material Type: Precision-machined from high-grade Aluminum Alloy 6061-T6.
• Gap Solution: Solves spacing issues where standard lengths fall short.
• Compatibility: Fits F34, EVT290S, and other brands utilizing the 290 mm square truss system. Exact fit with other manufacturers is not guaranteed.
• Durable Construction: Fabricated to withstand the compressive forces of the truss rig.

Designed by Evolve Truss, the EVT290A-CS20 allows riggers to fine-tune truss lengths without relying on loose shims or washers.

⚠️ Safety & Engineering Notice

❗ Critical Load Rating Information: The EVT290A-CS20 is a structural component. Do not exceed the load capacity of the spacer or the truss system it is modifying. 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.
• Handle truss segments and accessories with care—avoid dropping, dragging, or improper stacking.
• Assembly and installation must be performed only by trained and qualified personnel.
• 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, lighting plots, or other aluminum truss uses.

⚠️ Compatibility Warning for Mixed-Brand Builds

Crucial Steps for Safe Assembly:

• Verify all dimensions before integrating with other truss brands.
• Confirm conical connector type, node spacing, and system geometry.
• Mixing components without verification may compromise structural integrity and safety.
