I believe our crimper is made by Xcelite, not sure on the exact model, but something like
this.
I have purchased Paladin dies for it in the past (
like this one)
The dies you linked look like they would fit our crimper, and I saw them when I was searching, but do any of the ones listed work for the powerpole connectors? My impression was that this die set would allow you to crimp other style connectors with the TRIcrimp powerpole tool, but does not include the die that comes with the powerpole tool.
Plus I was looking for a single die, at $55 I might as well just buy the crimper I linked previously (which appears to be the tool that this set of dies is meant for).
