Free up space and secure power cords between rack-mount PDUs and attached IT equipment with this exclusive easy-to-use cord retention method. While this cord will fit into any standard IEC receptacle or power inlet, the "locking" feature is enabled only when used with APC AP8000 series Rack PDUs (available separately) or IT equipment with built-in locking receptacles. The locking connector reduces the probability of accidentally disconnecting a cord and dropping the load.
