The pipe rests upon the v-shaped replaceable steel jaws of the vice before the chain is secured around it.
The ribbed jaws work together with the chain to grip the pipe securely.
Chain
The high-tensile steel chain is looped over the section of pipe and secured between the jaws.
The chain’s ability to wrap tightly around the entire circumference of the pipe ensures that the pipe is clamped firmly in place so that it can be worked on.
Crank handle
When the crank handle is turned, the chain is tightened around the pipe until the pipe is immovable.
Pipe rest
Along with the jaws, the pipe rest supports the pipe so that it can be clamped to the vice.
Pipe bender
The pipe bender function of the vice means that the tool can be used not only to hold pipe but also to bend it.
However, this feature works best with plastic piping. For metal pipes, a specialised pipe bender should be employed.
Frame
The frames of most chain pipe vices are made of cast iron and have a corrosion-resistant coating.
Holes in the frame allow the vice to be clamped to either a workbench or tripod stand.
