Installation Guide

Position the Ethylene Propylene Diene Terpolymer (EPDM) Cold Shrink Tube KCTG-101 over the installation area, such as over the inline connection, joints, terminal lug, and terminal box. To install, pull and unwind the plastic ripcord in a counter-clockwise direction to unravel the spiral support core. This will allow the elasticity of the KCTG-101 to contract and conform into place.
