The Thexton Wire Insertion Tool Kit, No. 926, is great for installing wires for audio electronics, aftermarket lighting, alarm systems, remote start and more. The long steel tube provides enough access to feed wires through the other side of the firewall, even in marine applications. Having a sharp point and solid handle allow user to easily pierce through firewalls, rubber grommets and panels. The 3/8” tubing comes with a 35° bend which allows for more direction and control of pull through wire. The supplied special tubing allows user to feed tubing through the tool and is crimpable. This allows technician to crimp the new wire onto the pull through tubing, eliminating electrical tape bunches and messes.
