Sta-Kon WT1377 HD CRMP HANDTOOL NONINS HIGHTEMP

The WT1377 hand crimper covers 26 to 10 AWG, so it spans everything from fine control and signal wiring up through 10 AWG power conductors. If you're terminating conductors larger than 10 AWG, you need a heavier tool with the matching die range.

It's a non-insulated, high temperature terminal tool. The dies are set up for non-insulated terminals, splices and disconnects, so insulated vinyl or nylon barrel terminals should be crimped with an insulated-barrel Sta-Kon tool instead. Crimping an insulated terminal in non-insulated dies cuts the insulation sleeve and gives you an unreliable termination.

Terminals, splices and disconnects are all covered, in the non-insulated high temperature style. That's the typical mix on motor leads, appliance and HVAC wiring, and panel work where high temperature ring or fork terminals and butt splices are specified.

High temperature non-insulated terminals have a bare metal barrel, often with a ceramic or fiberglass sleeve added separately, and they need dies that compress the bare barrel without an insulation grip station. The WT1377 is that tool, rated 26 to 10 AWG. A standard insulated crimper has color-coded nests sized to the vinyl barrel diameter (red, blue, yellow) and will not form a correct crimp on a bare high temp barrel.

No. The WT1377 is a fixed-die manual hand crimper, not a frame-and-die system, so the nests for 26 to 10 AWG non-insulated high temperature terminals are part of the tool. One part number, one orderable configuration.

It's built as a heavy duty palm grip tool with orange handles, so the force comes off the palm rather than the fingertips. That's the layout electricians and panel builders prefer for repetitive runs of crimps on a control panel or fixture build. For true production volume you'd step up to a bench or hydraulic crimper.

Yes, country of origin on the WT1377 is the United States. That matters on government and institutional jobs carrying domestic sourcing requirements for tooling.
