Rigging clamps and couplers for hanging lighting fixtures from truss and bar. The Equinox TRC 100S is a self-locking aluminium easy clamp for 48-51mm tube with a 100kg safe working load, closed by a T-knob, supplied with an M10 bolt, washers and wing nut, and weighing 0.4kg. The ADJ O Slim 2 takes the opposite approach: a wrap-around O-clamp for 50mm tube rated at 13kg, slim enough to fit between the V braces of truss where larger clamps will not go, with the Mini O-Clamp covering smaller fixtures and tighter corners.

Match the clamp to both tube diameter and stated maximum load, which must exceed the fixture weight plus its accessories, and fit a rated secondary suspension on anything flown overhead: the Equinox 35cm safety wire here carries a 20kg rating.
