Truss Corner Reinforcement Knowledge Center
EVT290A-TCB Aluminum Corner Brace.
A 950 mm / 37.40 in Reinforcement Bar with 180-Degree Swivel Clamps for 50 mm Truss Chords.
The EVT290A-TCB is an aluminum corner reinforcement bar for bracing compatible 90-degree truss junctions. Its two Narrow Pro Clamps fit 48–51 mm tubing and swivel 180 degrees to support positioning on standard 50 mm / 2 in main chords. The brace is intended to help stiffen truss geometry and reduce flex, sway, and racking in reviewed ground-support structures, large display frames, staging, lighting, and event layouts. It is a reinforcement accessory only—not a lighting bar, rigging point, direct load-attachment location, or substitute for full structural design and required engineering review.
Product Facts
Product Overview
A Corner Brace for Reinforcing Compatible 90-Degree Truss Junctions.
The EVT290A-TCB bridges the inside of a compatible truss corner using a rigid aluminum bar and a Narrow Pro Clamp at each end. It is designed for use on 50 mm / 2 in main chords where the clamp range, bracing clearance, junction geometry, and complete structure have been verified. Its 180-degree swivel clamps support positioning, but the final installation must be appropriate for the actual corner, truss system, load arrangement, and approved structural plan.
What It Does
It Braces a Verified Corner. It Does Not Create a New Load Rating.
When correctly installed across a compatible 90-degree junction, the brace helps resist unwanted movement of the corner geometry. It does not independently establish permitted loading, span, pick-point location, support arrangement, or approval for the structure. Evaluate the complete assembled system, including the truss sections, connections, supports, loads, and installed brace.
Selection Guidance
Select the TCB When A Reviewed 90-Degree Corner Requires Additional Stiffening.
Use the EVT290A-TCB when a compatible ground-support structure, display frame, staging layout, lighting structure, or event build includes a reviewed 90-degree truss junction that requires corner reinforcement. Confirm that the truss has compatible 48–51 mm main chords, adequate diagonal-brace clearance, and a suitable location for the complete brace assembly.

System Compatibility
Compatible 50 mm Main Chords. Verify the Actual Tube, Clearance, and Corner Geometry.
The EVT290A-TCB is intended for compatible professional truss systems with 48–51 mm main chords, including the listed EVT290I, EVT290T, EVT290S, EVT12S, EVT20S, 290 mm, F34, and F33 contexts. Compatibility is not automatic. Verify actual tube diameter, clamp seating, diagonal-brace clearance, junction angle, structural layout, and the full installation before use.
Installation Checks
Inspect the Corner. Then Seat, Secure, and Review the Complete Brace Assembly.
Install the brace only after confirming that it is part of the reviewed corner-bracing plan. The bar must be straight, clamps and swivel mechanisms must be serviceable, both clamps must seat fully on compatible main chords, and all hardware must be tightened to the applicable manufacturer specification before loading or lifting the structure.
Safety and Engineering
A Corner Brace Reinforces Geometry. It Does Not Replace Structural Design.
The EVT290A-TCB is a structural reinforcement accessory for appropriate truss corners. It does not independently establish a load rating for the completed structure and is not a load-attachment point. Do not hang loads from the brace. Do not infer permitted span, loading, support arrangement, or approval from its installation. Evaluate the complete configuration, including the truss, connections, supports, load arrangement, and required engineering review.
Product Questions
Frequently Asked Questions.
What does the EVT290A-TCB do?
It is a corner reinforcement bar for bracing compatible 90-degree truss junctions to help reduce flex, sway, and racking in the reviewed complete structure.
Can I hang a light or rigging load from the brace?
No. The brace is reinforcement only. It is not a lighting bar, rigging point, or direct load-attachment location.
What tubing does it clamp to?
The stated Narrow Pro Clamp range is 48–51 mm tubing, intended for standard 50 mm / 2 in truss main chords. Verify the actual tube diameter and full clamp seating before use.
Do the clamps swivel?
Yes. The Narrow Pro Clamps have a stated 180-degree swivel range for positioning within a compatible verified corner arrangement.
What truss systems are listed as compatible?
The source identifies EVT290I, EVT290T, EVT290S, EVT12S, EVT20S, and compatible 290 mm, F34, and F33 truss-system contexts. Confirm actual tube fit, clearance, geometry, and structural suitability before installation.
Does the brace establish a load rating for my corner?
No. Permitted loading depends on the complete structure, including truss sections, supports, connections, loading arrangement, and required engineering review.
