The Light Source Quad Coupler 1.5 Parallel in black anodized finish is a robust structural rigging accessory used to join two sections of pipe or tube in a parallel configuration for professional stagecraft, lighting, and entertainment installations. This coupler is created by bolting together two standard Quad Coupler 1.5 units so that one’s flat (non‑keyed) face interlocks with the other’s keyed clamping surface, resulting in a secure connector that aligns both clamped members side by side rather than at an angle. Its black anodized aluminum body provides corrosion resistance and durability suited to both touring use and permanent installs where repeated setup and teardown are common.

Designed to grip round pipe or truss tubing with outside diameters from approximately 1.25 in to 1.50 in (including standard 1″ pipe), this parallel coupler offers flexibility when linking structural elements that must remain adjacent and aligned rather than forming a joint at an angle. The clamp’s geometry enables crews to construct rigid parallel runs of rigging pipe or tube without introducing twist or misalignment, which is particularly useful when creating straight fixture bars, support rails, or bracket bars beneath a grid or truss. The black finish helps it visually integrate with darkened stages or lighting rigs, reducing distractions and blending with professional hardware aesthetics.

The hardware set comprises a 3/8″‑16 tpi x 1.25″ socket head cap screw paired with a two‑way nylon locking nut, providing reliable clamp pressure that holds firm under vibration and load. With a working load limit up to 770 pounds, this coupler supports typical lighting and secondary attachment needs when installed per recommended rigging practice. Its ease of use and predictable performance make it a staple in event production toolkits where parallel pipe connections are frequently required.
