Note: E-390 is my inventory # only. Here is a good working pair of used Panduit CT-1550 ratcheting hand crimpers. They were last certified in 2002 and have been in a tool cabinet since. It comes with the two-size range die set of 22-14awg & 12-10awg all in one die set.
These will not release until the ratcheting mechanism completes it cycle and the crimp is properly made. The last photo with the red pointer shows there is an engraving lightly on the green handle.
