Secure Locking C20 (Male) to standard C19 (Female) data center grade power cord prevents accidental disconnect from devices. P-Locks are designed with locking clips on the sides of the connector keeping them firmly plugged in. The C20 P-Lock is a high quality design, that virtually eliminates chances of nuisance unplugging by latching into the C19 Inlet that it plugs into. This can be an essential solution for design teams looking to eliminate these moments of stress when a plug powering IT Equipment becomes unplugged. To unlatch the locked plug, pinch the tabs located on each side. Discuss with your team locations in your data center or server room where there is high traffic, and good candidates for such locking features.
