Maintain dependable power connections in tightly packed racks with this 4 ft IEC C19-to-C20 locking cable from UNC Group. Designed for equipment that requires a C20 inlet and a C19 source connection, it supports high-current deployments where secure retention matters. The locking design helps reduce accidental disconnects in environments where vibration, service activity, or cable strain can interrupt critical loads. The short 4 ft length is ideal for minimizing excess cable inside cabinets, which helps keep airflow paths clearer and simplifies front-to-back or side-to-side routing. The red jacket provides immediate visual identification, making it easier to trace power paths during maintenance, circuit changes, and outage response. For infrastructure teams managing servers, storage arrays, network appliances, or rack PDUs, this cable supports cleaner builds and faster serviceability. Choose this cable when you need a compact, high-current connection that fits enterprise rack standards without unnecessary slack. It is a practical fit for installations where cable discipline, retention, and quick identification directly affect uptime and operational control.
