The The Light Source Mega‑Slim Coupler Counter Sunk Metric, Black Anodized with a 3/8″ × 1″ flat head bolt is a compact, low‑profile pipe and truss clamp designed for professional entertainment rigging where a lighter, less obtrusive solution is desired. Engineered by The Light Source, this coupler is a slimmer alternative to their standard Mega‑Coupler, weighing significantly less while still fitting the same pipe and tubing diameters. Its reduced thickness and aesthetic black anodized finish make it well suited for setups where visual minimalism and reduced obstruction are priorities — such as lighting positions, camera mounts, or auxiliary rigging points in concert, stage, and event environments.

At its core, this coupler clamps securely around round pipe or truss tube by tightening the included flat head bolt, which is recessed into the body to present a cleaner profile than typical protruding bolts. The countersunk 3/8″ × 1″ flat head bolt not only complements the slim design but also allows the use of an Allen key for tightening, offering a smooth exterior that minimizes snagging. A spring (Belleville) washer and nylon lock (nylock) nut paired with the bolt help maintain clamping pressure under vibration or movement, providing riggers with confidence in the stability of their setup.

Functionally, this Mega‑Slim Coupler clamps pipe and truss in the same diameter range as larger couplers but does so with reduced bulk, making it ideal for lightweight rigging tasks where space is limited or visibility is important. Its design accommodates most standard structural pipe sizes used in the live events industry and offers a practical mix of strength and compact ergonomics. Whether securing instruments, mounts, or scenic elements, this coupler gives technicians a reliable clamp that adds minimal visual or physical weight to a rigging build.
