The Light Source Mega-Coupler with CS Base is an integrated mounting solution that combines a heavy-duty pipe coupler with a flat, perforated center socket base plate. Finished in a matte black anodized coating, this component is engineered to create a secure, upright post from a single length of 1.5-inch schedule 40 steel pipe while providing a stable foundation for anchoring to a floor or platform. The coupler portion grips the pipe's 1.9-inch outer diameter via a combination of a set screw and a central 1/2-inch flat head bolt that passes vertically through the base and the coupler body. This through-bolt is secured by a large wingnut or hex nut, applying additional downward clamping force to lock the pipe against the base plate, thereby preventing lift and rotation.

The CS (Center Socket) base is a critical feature, offering a broad, flat steel plate with multiple holes for fastening to wooden stages, concrete floors, or other structural surfaces using appropriate lag bolts or concrete anchors. This design distributes the load of the vertical pipe over a wider area, significantly enhancing the stability of the freestanding assembly against tipping forces. The black anodized finish on both the coupler and base provides a durable, corrosion-resistant surface that is both aesthetically neutral and suitable for demanding environments. This unit is a complete, ready-to-install anchor point, eliminating the need to source and assemble separate base plates and pipe clamps.

This product is indispensable for constructing portable yet sturdy vertical supports for lighting, signage, drapes, and sensors in theatrical, event, and exhibition settings. The combination of the Mega-Coupler's firm grip and the CS base's secure footing allows for the creation of safe, load-bearing structures without permanent installation. The inclusion of the 1/2-inch flat head bolt and matching hardware ensures a redundant locking mechanism, offering installers confidence in the joint's integrity under dynamic loads. It represents a versatile and robust foundation system that prioritizes both ease of assembly and structural safety.
