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 these cords will fit into any standard IEC receptacle or power inlet; the “locking” feature is enabled only when used with APC AP8000 series Rack PDUs or IT equipment with built-in locking receptacles. These locking connectors reduce the probability of accidentally disconnecting cords and dropping loads.
