The Light Source Quad Coupler 1.5 in black anodized finish is a compact yet versatile rigging clamp designed for use in professional event production, staging, and entertainment industry installations. Engineered to provide a strong mechanical grip on standard structural tubing and pipe, it offers technicians a reliable way to attach accessories, screens, or secondary hardware to round pipe and truss. Its reduced thickness and black anodized surface make it ideal for environments where aesthetics matter, such as theatre rigs, concert staging, and broadcast sets, while still delivering robust performance.

Constructed from precision‑machined aluminum with a corrosion‑resistant black anodized coating, the Quad Coupler 1.5 clamps securely around tubes with outside diameters from approximately 1.25″ up to 1.5″, as well as standard 1″ pipe. Its versatile design includes a notched face that can lock parallel to square tube or provide a flat surface for mounting fixtures directly, allowing crews to adapt it to a variety of rigging tasks with ease. The coupler comes complete with a 3/8″ × 1.25″ socket head cap screw, nylon insert lock nut, and a Belleville spring washer to help maintain firm clamp pressure under load and vibration.

In practical use, this coupler serves as a fundamental building block in many structural setups, whether joining tubes, mounting lighting accessories, or providing connection points for secondary hardware. Its modest size and half‑pound weight make it easy to handle on the rigging floor, and its 770 lb working load limit gives crews confidence that it will hold reliably when installed according to industry safety practices. The combination of compact form, flexible attachment options, and rugged construction makes the Quad Coupler 1.5 a popular choice for professionals requiring dependable rigging hardware.
