Altman 510 Malleable Iron Pipe Clamp enables attachment of almost any lighting fixture. The lighting fixture should consist of a flat blade yoke to an overhead pipe, or
tubular truss. The clamp adjusts to pipe diameters 0.75" - 1.5", and includes 0.5"-13 fixture attachment bolt. For over fifty years, the Altman name has stood true as one of the leading innovators of theatrical, architectural, film, and video lighting.
