Terminations have a professional finished look.you will love the way this goes perfectly with the connector end and makes for a very clean, great looking cable when completed. AVOID PATCH CORD KINKSIt stops those connector kinks that ruin your patches prematurely.Extend patch cord life.Nice to be able to block the latching mechanism from being caught on something if someone pulls it through a mess of wires or against the floor. EASY TO INSTALLIt works fine with passthrough plugs from different manufacturers.Very easy to use.
