The Light Source Maffer Pin Adapter is a heavy-duty interface component designed to connect equipment with a standard 1/2-inch-13 threaded fitting to a maffer clamp system, a common rigging hardware used in theatrical and event production for securing pipe. This adapter is constructed from solid steel or brass and finished in a durable silver plating or coating, providing high strength and corrosion resistance. Its design typically features a cylindrical body with a male or female 1/2-inch-13 thread on one end, and a precision-machined cylindrical pin or post on the opposite end. This pin is engineered to fit securely into the jaw of a standard maffer clamp, which is then tightened to lock the adapter—and consequently any attached equipment—firmly in place on a pipe or truss.

This adapter serves as a critical bridge between specialized rigging hardware and a vast array of threaded accessories. By screwing a lighting fixture, speaker, or other device with a 1/2"-13 mounting thread directly onto the adapter, the user can then employ the powerful gripping force of a maffer clamp to mount that entire assembly onto a structural pipe. This combines the positional flexibility and strong hold of a maffer clamp with the universal compatibility of a standard threaded connection. The silver finish ensures the adapter matches other common silver-toned rigging hardware and provides a layer of protection against the elements in both indoor and outdoor applications.

The product is essential for riggers and technicians building complex overhead systems. It enhances safety by ensuring a secure mechanical link between the equipment and the clamp, and it increases efficiency by standardizing connections. The adapter is built to handle substantial loads, with its solid metal construction capable of withstanding the stresses of suspended equipment. Whether used for hanging moving lights on a tour, mounting projectors in an installation, or securing signage in an exhibit, the Maffer Pin Adapter provides a reliable, robust, and reusable solution for integrating threaded equipment into pipe-based structural grids.
