The Light Source Mini-Clamp is a compact and versatile fastening device designed for securing lightweight tubing, cables, or small accessories within technical and audiovisual setups. This small but sturdy clamp features a classic two-piece "C" shape design, typically constructed from durable steel or robust polymer, and finished in a universal matte black. Its primary function is to provide a secure anchoring point by clamping onto poles, bars, or edges of surfaces with thicknesses suitable for its limited jaw capacity. The clamp halves are joined by a bolt and wing nut or a thumb screw assembly, allowing for quick, tool-free operation—the user simply positions the clamp around the object and tightens the screw by hand to achieve a firm, non-slip grip.

Despite its miniature size, the clamp is engineered for practical utility in organizing and mounting equipment. It often includes an integrated standard 1/4-inch-20 or 3/8-inch threaded mounting point on its back, enabling it to function as an adapter. This allows various small accessories, such as LED puck lights, microphones, gobo holders, or cable strain reliefs, to be attached to the clamp itself, which is then secured to a convenient standoff or crossbar. This dual functionality makes it an indispensable item for solving minor rigging challenges on the fly, particularly in confined spaces where larger hardware would be impractical or obstructive, such as inside equipment racks, on small diameter tubes in trade show displays, or along the edges of furniture and shelves for temporary lighting.

The black finish ensures the clamp maintains a low visual profile, blending into the background of most equipment and environments. Its value lies in its simplicity, adaptability, and the organizational clarity it brings to complex cable runs and equipment arrangements. Photographers, theater technicians, and studio engineers frequently use these clamps for managing wire looms, positioning small fixtures, or creating improvised mounts, appreciating their ability to provide a reliable hold without damaging the surface they grip. The Light Source Mini-Clamp exemplifies how a modest, single-purpose tool can significantly enhance workflow efficiency and creative problem-solving in dynamic technical environments.
