Sound Barrier ST292AWCBBLK 290mm Black Aluminum Box Truss Corner — TUV-Certified Structural Corner Block
ST292AWCBBLK Overview
The Sound Barrier ST292AWCBBLK is a 290mm black aluminum box truss corner engineered for professional ground support, touring rigs, and permanent installation structures. Constructed from aluminum with a 50mm tube diameter and 2mm wall thickness, this corner block delivers the structural integrity required in demanding live event and fixed installation environments. The ST292AWCBBLK carries TUV certification from a nationally recognized testing laboratory (NRTL), providing third-party verification of safety and load performance. It is suited for system integrators, touring production companies, staging contractors, and houses of worship requiring code-compliant overhead and ground support structures.
The black finish integrates cleanly into stage and architectural environments where visual discretion is a priority, and the corner geometry is designed to work within the broader Sound Barrier 290-series truss ecosystem.
