Geist C19 IEC - C20, 1m Blue C20 coupler

Because the locking cord sets are compatible with any IEC power inlet, cords can securely attach to most any device in a data center. The locked cord is easily released by sliding the tab located on the C13/C19 connector. There are no special tools or equipment required. IEC standards allow cord removal forces as low as 1 pound of force. This modest requirement means non-locking plugs could conceivably fall out easily from the weight of their cord alone. The security of locking cord sets is a must for environments with stringent uptime requirements.
