A 950 mm / 37.40 in Bar with 180-Degree Swivel Clamps for 50 mm Truss Chords.
The EVT290A-TCB is an aluminum corner brace for use across compatible 90-degree truss corners. It has two Narrow Pro Clamps that fit 48–51 mm tubing and swivel 180 degrees for positioning on compatible standard 50 mm / 2 in main chords. The brace is a corner accessory for a documented truss layout. It is not a lighting bar, rigging point, hanging bar, separate support, or direct attachment location for loads. Confirm tube fit, clearance, clamp seating, clamp tightening, and the complete installation before use.
Product Facts
Product Overview
A Corner Brace for Compatible 90-Degree Truss Corners.
The EVT290A-TCB spans the inside of a compatible truss corner with an aluminum bar and a Narrow Pro Clamp at each end. It is intended for use on compatible 50 mm / 2 in main chords where the clamp range, clearance, corner arrangement, and complete installation have been confirmed. The 180-degree clamp swivel allows clamp orientation adjustment for a compatible corner arrangement; do not force the bar or clamps into a corner arrangement that does not fit.
What It Does
It Spans a Compatible Corner. Confirm the Complete Installation.
The TCB is used across a compatible 90-degree truss corner as part of a documented layout. It does not by itself determine the use, loading, span, support arrangement, or installation requirements for the completed assembly. Check the complete truss installation, including its sections, connections, supports, equipment placement, and installed corner brace.
Selection Guidance
Select the TCB When A Compatible 90-Degree Corner Calls for This Brace.
Use the EVT290A-TCB when the documented layout calls for a corner brace at a compatible 90-degree truss junction. Confirm that the actual main chords measure within the 48–51 mm clamp range, diagonal bracing does not block clamp placement, and the 950 mm bar fits the intended corner location.

System Compatibility
Compatible 50 mm Main Chords. Verify the Actual Tube and Corner Clearance.
The EVT290A-TCB uses Narrow Pro Clamps stated for 48–51 mm tubing and is intended for compatible 90-degree truss-corner applications. Do not infer compatibility from tube diameter alone. Verify actual tube diameter, clamp seating, diagonal-brace clearance, corner geometry, connection details, and applicable manufacturer documentation before use.
Installation Checks
Inspect the Corner. Then Seat, Secure, and Check the Complete Brace Assembly.
Install the brace only after confirming that it is part of the documented corner plan. The bar must be straight, clamps and swivel mechanisms must be serviceable, both clamps must seat fully on compatible main chords, and clamp hardware must be tightened according to current manufacturer instructions before the installation is used.
Safety and Use Limits
A Corner Brace Is Not a Hanging or Rigging Bar.
The EVT290A-TCB is a corner accessory for compatible truss corners. Do not use it as a lighting bar, rigging point, hanging bar, cable support, separate support, or direct attachment location for loads. Confirm the complete installation, including the truss, connections, supports, load arrangement, and brace placement, before use.
