JAWS 3 are a set of aluminum-nickel-bronze vise jaws designed to replace the regular jaws in a RIGID #23 or #40-A pipe vise. JAWS 3 are designed for use with Plasti-Bond Coated Conduit. They completely protect the exterior coating from damage caused by the vise jaws when cutting or threading. One set of JAWS 3 handles Plasti-Bond Coated Conduit sizes from 1/2" through 1-1/2". Model #23 fits the RIGID #23 pipe vise. Model #40-A fits the RIGID #40- A tripod pipe vise.
