Do you think this will grip tightly to 3/4" black ...

Do you think this will grip tightly to 3/4" black pipe, or too big?
Asked by: Eric
I'd likely use a Cardellini clamp to secure a light to a 3/4" OD black iron pipe. If the head is small like a ARRI 150 or 300, a Lowell clamp would work. If all you have is a standard baby pipeclamp and you need it to bite a smallish pipe you can place a small hardwood block between the pipe and the bolt, and then tighten your bolt. For this to work safely the pipe must settle into one of the corners of the clamp. Be sure to use a wire safety to connect the pipe to the yoke of the instrument in case the bite fails.

I plan to secure lights to the metal roof truss in the studio. Is this clamp appropriate for this application?
Asked by: Jeff
No, this is a pipe clamp. You could try a truss clamp (available at local plumbing supply) with a screw-in 5/8 stud.

we are building the pipe grid now but i need to give the pipe dimensions to the architects....what size pipe is best?
Asked by: Anonymous
We used 2 aluminum pipe, which has served quite well. The pipe wall is thick, at least 1/4 , probably 3/8 , to resist deformation from tightening the clamp. The outside surface is not smooth, but has longitudinal ridges, which helps prevent slippage. A local machine shop supplied the pipe and built 4 grids for us.
