Universal Chain Clamp -
The “Sliding Jackbar” design of the Universal
Chain Clamp allows the Jackscrew to be positioned on either side of the weld.
This allows 100% welding and grinding without removal of the clamp. The
clamp is ideal for the alignment and reforming of pipes, elbows, tees, and
mitered joints – up to Schedule 40 pipe. It is capable of aligning pipe to
Schedule 80 if reforming is not required.
Mini-Fit -
is used for fitting-up and aligning small diameter pipe. Its
lightweight and simple design makes the Mini-Fit ideal for light duty
applications, where “out-of-round” problems do not exist. The Mini-Fit is
excellent for use on conduit, copper pipe, and thin wall pipe or tubing.
Sturdi-Clamp Chain Clamp –
The Sturdi-Clamp is ideal for Schedule
40 & below pipe alignment and reforming. Lighter weight than the original
Mathey Dearman Chain Clamps. The Sturdi-Clamps are quick and easy to setup
while still providing the ability to get excellent fit-ups on pipe from 1” to 36”.
