GadKo Cat6 RJ45 Crimp Connectors for Solid and Stranded Cable, 8P8C, 100 Pieces GadKo is the only authorized dealer of GadKo branded products. These crimp connectors are used to terminate a CAT-6 cable. The wire insertion guide is fixed inside of the connectors and cannot be removed. It features a staggered insertion as the individual wires of CAT6 are too thick to be arranged in a straight line as with CAT5E connectors.
