The Light Source 16" Mega-Beam Clamp is a heavy-duty, professional-grade rigging component designed for secure and reliable overhead mounting of lighting, audio, and production equipment to structural I-beams. Engineered for demanding applications in theatrical, concert touring, film production, and permanent architectural installations, this clamp is rated for an impressive 3-ton (6,000-pound) safe working load, providing a significant safety margin for suspending heavy trusses, motor assemblies, or large lighting fixtures. Its core design features a robust, forged steel body finished in a durable black anodized coating for corrosion resistance and a low-profile appearance. The 16-inch measurement refers to the length of the forged steel "T-bolt," which is the primary threaded shaft that passes through the beam's web—the vertical section of an I-beam—to engage with the clamping mechanism on the opposite side.

The clamping action is achieved through a powerful leverage system. The long T-bolt is inserted through a pre-drilled hole or the open web of the beam, and a forged steel saddle plate is placed against the far side of the web. A massive, forged steel hex nut is then threaded onto the T-bolt. Using a large spanner wrench, this nut is torqued down, drawing the main clamp body and the saddle plate together, which pinches the beam's web securely between them. This creates an immensely strong, friction-based grip that resists sliding, rotation, and dynamic loads. The clamp body itself incorporates a standard 1.5-inch diameter schedule 40 pipe stub, which allows for the direct attachment of a vertical or horizontal pipe, a truss corner, or a half-coupler, providing a versatile and solid mounting point.

This clamp is intended for use by qualified riggers and production professionals who understand load dynamics, safety factors, and local regulations. Its 3-ton rating assumes proper installation on a structurally sound beam that can support the intended load. The Mega-Beam Clamp's combination of massive strength, a 16-inch bolt length capable of accommodating very thick beam flanges and additional hardware, and its standardized pipe connection makes it an indispensable tool for constructing safe and stable overhead rigging points in the most challenging and weight-critical production environments.
