Product Description
10mm (0.39″) Aluminum Truss Coupler Spacer – Male to Male Coupler Expansion Insert – Matte Black Finish (EVT290A-CS10 Black)
The EVT290A-CS10 Black is a specialized double-ended male conical coupler designed for 290 mm square conical aluminum truss systems. Finished in a professional matte black powder coat, this unit is essential for discrete installations where silver hardware would stand out visually. As a direct replacement for a standard coupler, it features a machined central collar that adds exactly **10mm (0.39″)** to the length of the truss span, providing a secure, male-to-male structural connection while extending measurements 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 10mm 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 black 290mm truss brands.

⚠️ Safety & Engineering Notice
❗ Critical Load Rating Information:
- Structural Integrity: The EVT290A-CS10 Black 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
