Used for hanging equipment with smaller mounting holes or threads including camera rigs, tripod heads and smaller lights to pipe grids and truss. Includes a 3/8" mounting bolt with locking nut. For standard theatrical fixtures, use the 1/2" version. Has a slightly larger diameter than grid clamps which allows it to attach to standard 2" Truss.
