Plug-lock Inserts keep C14 power cords solidly connected to C13 outlets- 100pk Tripp Lite PLC13RD RED color Plug-lock inserts prevent accidental disconnection of C14 plug-in power cords from C13 output receptacles.

To prevent critical equipment plugs from getting knocked loose, place a Plug-lock insert over any C14 input cord and connect it to any C13 outlet. The insert strengthens the connection of the plug to the outlet, keeping critical equipment plugged-in and running during routine rack access and maintenance. Plug-lock inserts provide a no-clutter alternative to common zip-tie cord retention schemes and a low cost answer to expensive proprietary locking plug and outlet hardware.
