A half coupler, also called a barrel clamp — a clamp that closes around a 48–51mm scaffold or lighting bar and gives you a fixing point on it. This one carries a 16mm (5/8″) baby stud, the standard peg that lightweight luminaires, grip heads and most studio accessories socket onto. Maximum load 100kg.

Made from 6061 T6 high-tensile aluminium extrusion. The clamp closes with a wing nut on a threaded bolt, and the bolt is captive, so the wing nut cannot spin all the way off and drop while you are working overhead.
