The 12" Truss Grapple Bar is a specialized connector designed to facilitate 90-degree inline or perpendicular joins between standard 12" box trusses. Commonly used in stage rigging and structural event setups, it enables secure and stable truss configurations without the need for corner blocks. Constructed from high-strength aluminum alloy, the grapple bar includes integrated mounting hardware and is engineered to maintain structural integrity under load. Proper installation requires qualified rigging personnel, and all truss segments must be supported at both ends to avoid cantilevering (this unit must be rented in pairs).
