This is a locator for Tyco contacts to be used with Rennsteig PEW 12 crimping pliers. The Locator holds the terminal in the tool so that you don't need 3 hands to make a crimp. It also positions the terminal so you always crimp it in the right place, for a high-quality connection every time. The Tyco locator is designed for AWG 16/14/12/10.
This part is often purchased with the Rennsteig All For One Kit, see related parts to the right. Rennsteig PN: R624 817 0 01
