IRWIN Pipe Clamp, 3/4"

Used these on a 10-foot glue-up and the clutch held tight without slipping once I got the pipe cut to size. Being able to grab any length of black pipe is the whole reason I switched to this style. Cheaper than buying a bunch of fixed-length clamps too.

The clutch system on these actually holds tight — I clamped a warped oak panel overnight and it didn't slip a bit. Slid them onto a 4-foot pipe I had in the shop and suddenly I've got clamps longer than anything I could buy off the shelf.

Picked up two of these to glue up a walnut tabletop and the 3/4" size fits standard black pipe perfectly. Being able to cut pipe to whatever length I need beats buying fixed-size clamps. The jaws bit down hard and didn't slip once.
