U31RT 12-Ton Crimping Die for 350 kcmil Copper Lug

The Burndy U31RT is a U-style upper and lower crimping die designed for 350 kcmil copper lugs. It suits electricians and technicians making permanent compression connections on large-gauge copper cable. The single die set handles one crimping size with a red colour code for quick identification. It is built for professional electrical and utility work.

Practical Limits of 12-Ton U-Style Tooling

This die requires a 12-ton compression tool with U-style die acceptance to operate. It is compatible with 35 Series and 750 Series tools including PAT46, PAT750, PUADP1, Y35, Y46 and Y750 models. The die cannot be used with tools below 12-ton capacity or with non-U-style die systems. It is restricted to copper connectors type YA and YS only.

Replacing Worn Dies or Adding 350 kcmil Capacity

The U31RT replaces a worn or damaged 350 kcmil die to restore reliable crimp quality on existing 12-ton U-style tools. It also adds 350 kcmil capability to a compatible tool that previously lacked this size. The jump is worth it when current tooling cannot produce the red-coded crimp required for 350 kcmil copper lugs.

  • 12 ton force handles heavy-duty connections

Questions about this item

Which die matches a 350 kcmil copper lug?

The U31RT is stamped for a single 350 kcmil copper lug with a red colour code.

What does the 12-ton rating mean when I am crimping?

It requires a 12-ton tool such as the PAT46, PAT750, Y35, Y46 or Y750 to reach full compression on that lug.

Will this U-style die fit my 35 Series or 750 Series tool?

Yes — it is listed for both the 35 Series and 750 Series, plus the PUADP1 adapter.
