Sound Barrier ST29220BLK 290mm Black Aluminum Box Truss Segment 2m — TUV-Certified Professional Truss
ST29220BLK Overview
The Sound Barrier ST29220BLK is a 2-meter section of 290mm square aluminum box truss finished in black, designed for professional touring, staging, and permanent installation environments. Constructed from 50mm diameter aluminum tubing with a 2mm wall thickness, this segment delivers the structural integrity required for demanding live event and fixed installation applications. The 290 x 290mm cross-section provides a robust geometry suited for lighting rigs, audio arrays, and ground support systems. TUV certification from a nationally recognized testing laboratory (NRTL) confirms that this truss meets rigorous third-party safety standards, making it a reliable choice for system integrators, production companies, and venues with strict compliance requirements.
The black finish integrates cleanly into stage designs where visual discretion is a priority, and the standardized 2-meter length simplifies modular system planning and inventory management.
