About the The Light Source 10" Mega-Beam Clamp, 3 Ton, Silver
The Light Source 10" Mega-Beam Clamp is a heavy-duty industrial-grade rigging component designed for securing lighting, audio, and scenic elements directly to the structural steel I-beams commonly found in warehouses, convention centers, and theatrical fly systems. Engineered for a formidable 3-ton (6,000 lb) safe working load, this clamp provides a reliable and code-compliant method for creating secure overhead attachment points without the need for drilling or welding into the beam itself. Its 10-inch height provides significant clearance between the top of the beam and the attachment point, allowing ample space for the clamp's mechanism and for routing cables cleanly beneath the beam flange. The silver finish, typically a durable zinc plating, offers corrosion resistance for long-term use in various environments.
The clamp operates on a secure mechanical principle. It consists of a heavy steel plate or yoke that hooks over the top flange of the I-beam. A substantial forged or machined jaw assembly, tightened by a high-strength alloy steel bolt (often requiring a large wrench or ratchet), applies immense force to the underside of the beam's lower flange. This creates a powerful clamping action that securely sandwiches the beam's web between the upper hook and the lower jaw. The immense force and large surface area distribute the load safely, preventing slippage and protecting the beam's finish. The clamp is typically outfitted with a standardized attachment point, such as a 5/8-inch receiver pin or a large eye bolt, from which other rigging hardware like shackles, turnbuckles, or hanging rods can be connected.
Designed for safety-critical applications, this clamp is a fundamental tool for professional riggers and production teams working in empty venues where traditional theatrical pipe grids are not available. Its 3-ton rating provides a substantial safety margin for suspending heavy truss sections, large speaker arrays, or complex lighting structures. The Mega-Beam Clamp allows for the rapid and temporary—yet extremely secure—installation of production equipment to the building's inherent structure, forming the foundational anchor point for entire temporary overhead systems. Its robust design and clear load rating make it an indispensable piece of hardware for large-scale event production, film and television studio rigging, and permanent architectural installations requiring secure beam attachments.
