Altman 510 Malleable Iron Pipe Clamp enables attachment of almost any lighting fixture. The lighting fixture should consist ofa flat blade yoke to an overhead pipe, or tubular truss.The clampadjusts 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.
I bought these to hang a few Optikinetics Solar 250 lamps. Perfect, they are easy to adjust have a full range of pan and tilt. You hang the lamp then tighten it into position, unlike some other clamps that don't stay on the bar until you tighten them.
Altman 510 is a great design, this is the classic C-Clamp for lighting fixtures, there isn't anything better ( That I know of)
