TrippLitePDUTripp Lite, Chicago, has introduced PDU Plug-lock Inserts for preventing accidental disconnection of C20 and C14 plugs. Often loose fitting, IEC plugs can be accidentally disconnected by even the slightest nudge or vibration, a likely event during routine network maintenance. The plug-lock inserts fit over the input plug, ensuring a secure connection between the plug and the outlet, with up to 10 times more retention force than standard connections. Offered in black, blue, and red for color-coding, the inserts are compatible with any manufacturer’s cord.
