The Light Source Mega-Clamp Black with 2" Long Bolt is a heavy-duty rigging clamp engineered for securing lighting fixtures and production equipment to large-diameter pipes, trusses, or structural beams. This variant of the Mega-Clamp is distinguished by its inclusion of an extended 2-inch-long primary bolt, which provides a greater thread engagement and clamping range. This is particularly advantageous when attaching the clamp to thicker materials, such as schedule 80 pipe or large timber, or when additional space is needed for safety hardware like a lock washer. The black finish, typically a durable powder coat or anodization, offers a non-reflective, professional appearance that is preferred in theatrical and event environments to minimize visual distraction and light spill. The clamp is constructed from forged or machined high-tensile steel, ensuring it can withstand the significant static and dynamic loads associated with suspending heavy moving lights, LED panels, or scenic elements.

The clamp's design incorporates a wide, deep jaw that accommodates substantial support structures. The extended 2-inch bolt is the core of the clamping mechanism, driven by a large T-handle or hex-head to generate immense force, securely gripping the pipe without damaging its surface. A critical integrated safety feature is the secondary locking pin or bolt, which acts as a fail-safe to prevent accidental release of the fixture should the main clamping pressure be compromised. The top of the clamp is fitted with a standard 5/8-inch receiver pin or a threaded stud, providing a universal interface for attaching lighting fixture yokes or other rigging hardware. The extended length of the main bolt enhances the clamp's versatility and security, allowing it to be used in a broader range of structural scenarios with confidence.

This clamp is a fundamental tool for professional riggers in concert touring, theatrical production, and permanent installation. The added length of the bolt addresses specific challenges posed by oversized or irregularly shaped support members, ensuring a secure connection even in non-standard situations. When used as part of a complete and rated rigging system, the Mega-Clamp Black with 2" Long Bolt provides a reliable and robust anchor point, giving technicians the assurance that valuable and potentially dangerous overhead loads are held securely in place.
