Global Truss SQ-4121 90-Degree Corner Truss

The Global Truss SQ-4121 is a box-style truss corner segment engineered to join two truss runs at a precise 90-degree angle. Built by TÜV-certified welders, it meets stringent European safety and quality standards, making it a dependable structural component for professional lighting rigs, exhibition booths, and stage setups. Each arm extends 0.5 meters from the corner junction, and the piece ships with all necessary connecting hardware so it can be integrated into an existing SQ-series truss layout without additional sourcing.

As a 2-way corner, the SQ-4121 serves a focused role in truss design — creating clean right-angle turns in horizontal or vertical planes. Its steel box-truss construction delivers high load-bearing capacity and rigidity, which is critical when suspending lighting fixtures or other heavy equipment. For installers who work regularly with the Global Truss SQ system, having dedicated corner segments like this one simplifies builds and ensures consistent, repeatable geometry across events.
