The Light Source Quad Coupler 1.5 90 Degree in silver is a rugged and versatile rigging accessory designed to facilitate strong, right-angle connections between structural tubes and pipes in professional staging, lighting, and truss systems. It is built by interlocking two individual quad coupler halves so that their keyed clamping surfaces mesh together, creating a secure mechanical joint that resists rotation and maintains alignment under load. This configuration makes it especially useful for constructing rigid 90-degree intersections within truss frameworks or when attaching ancillary structural elements to a main grid.

Constructed from precision machined aluminum with a silver finish, this coupler is sized to clamp standard tubing up to 1.5 in outer diameter and accommodate smaller pipe sizes as well, offering flexibility for use across a range of rigging setups. The design incorporates industry-standard fasteners that ensure positive clamp engagement while simplifying installation and removal during setup or reconfiguration. Its robust construction and thoughtful engineering reflect the needs of professional riggers who demand reliable hardware for events, concerts, and temporary installations that must withstand repeated use.

Functionally, the Quad Coupler 1.5 90 Degree serves as a fundamental building block in truss assembly, enabling secure orthogonal joints without compromising on load-bearing capacity. Its right-angle orientation provides predictable geometry for constructing grids, supports, and framework intersections, which is critical when precise load paths and spatial relationships are required. The product’s combination of strength, versatility, and ease of use makes it a staple in the toolkit of lighting and rigging professionals.
