The Light Source Quad Coupler 1.5 90 Degree in black anodized finish is a professional‑grade structural clamp engineered to create strong right‑angle connections between round pipe or tube in entertainment, staging, lighting, and rigging applications. It is produced by joining two standard Quad Coupler halves so that their keyed clamping faces interlock, forming a secure, 90° joint that resists rotational forces once tightened. The elegant black anodized surface not only enhances corrosion resistance and durability but also provides a low‑profile, unobtrusive appearance that fits well with modern staging aesthetics.

Designed to accommodate common rigging sizes, this coupler clamps onto structural tubing and pipe ranging from smaller lighting grid elements up to mid‑sized truss members. Its machined aluminum body delivers sufficient strength for a range of lightweight to moderate loads found in stage lighting, scenic elements, and secondary hardware attachments. The right‑angle configuration simplifies layout and alignment tasks by providing predictable geometry where perpendicular connections are required, such as joining horizontal and vertical runs or creating T‑frame intersections.

The hardware included — a socket head cap screw paired with a nylon locking nut — ensures firm clamping force while helping resist loosening from vibration or handling during installation. The straightforward bolt‑on design allows rigging crews to install and remove the coupler quickly with common tools, improving efficiency on busy production floors. With its combination of lightweight construction, reliable holding capacity, and clean black finish, the Quad Coupler 1.5 90 Degree is a staple accessory for professionals needing dependable 90° pipe‑to‑pipe or tube‑to‑tube joints.
