TRANSPARENT EXCELLENT STRAIN RELIEF. Not particularly troublesome to put on. Outside diameter of 6.5 mm fits wires from 24AWG to 26AWG round cable. The jacks clamp enough to grip the strain relief. These strain reliefs help to make sure that nobody can pull the cable out while not pulling from the connector itself and not get the pressure sensitive tab caught while pulling through debris or other cables.. CARD BUCKLE DESIGN. It makes the connector hard to drop and easy to connect. Nice add on to make a proper connection. Great add on to the connector.
They make connections look more professional and eliminate snagging and braking the release tab when pulling or untangling wires.. AVOID PATCH CORD KINKS. It 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.
