The Light Source Micro-Clamp is a compact, versatile fastening device designed for securing lightweight to medium-duty applications in staging, exhibitions, and general fabrication. The inclusion of black zinc-plated bolts specifies a particular hardware finish, indicating that the clamp's fasteners are steel bolts treated with a zinc coating and a subsequent black chromate conversion layer. This finish provides significantly enhanced corrosion resistance compared to plain steel, along with a durable, dark appearance that reduces light reflection and offers a professional look. The clamp itself is a small, typically U-shaped or flat-bar style component, engineered to join two perpendicular members, such as attaching a pipe to a flat surface or connecting two pipes at a right angle. Its "micro" designation refers to its smaller size and load capacity relative to larger industrial clamps, making it ideal for detailed work where precision and a low-profile connection are required.

The design of the Micro-Clamp is centered on simplicity and effectiveness. It usually consists of a single-piece body with pre-drilled holes that align with the black zinc-plated bolts. One section of the clamp wraps around or secures against the primary support member, while the bolt is passed through the clamp and tightened to pinch or press against the secondary member being mounted. The black zinc plating on the bolts not only protects against rust but also ensures the fasteners maintain their integrity and appearance over time, even with frequent assembly and disassembly. The clamp body may be made from stamped steel, aluminum, or a similar durable metal, and is often finished to match or complement the bolts. This hardware combination allows for a strong, rigid connection that can be easily adjusted or removed with standard hand tools.

This clamp is extensively used in constructing small-scale structures, such as display stands, retail fixtures, light-duty shelving, and temporary electrical mounts. In theatrical and event production, it is invaluable for attaching small lighting accessories, cable guides, or signage to truss and tubing without the need for heavy, bulky hardware. The black zinc bolts contribute to a cohesive, finished appearance, making the clamp suitable for front-of-house applications where visible hardware must be unobtrusive. For technicians and fabricators, the Micro-Clamp represents an essential, reusable piece of hardware that offers reliability and flexibility, enabling quick modifications and sturdy assemblies in a wide array of lightweight mounting scenarios.
