HDMI Port Lock Helps Prevent Accidental Disconnection and Expensive Downtime Having a cable come loose accidentally can mean the loss of an audio/video signal and costly downtime. The P568-000-LOCK helps you avoid interruptions in your digital signage system by maintaining a secure link without failure. A locking HDMI connection is also invaluable when moving equipment in a rack or removing equipment from tight areas, ensuring the cable always stays connected. Easy to Install in Just a Few Minutes This HDMI lock works with any HDMI cable and any device with a fixing or locking screw space above or below the HDMI port. If the device has no screw in the fixing space, one is included. Just secure the included nylon cable tie to the fixing space with the screw, and insert your HDMI cable into the cable tie clamp, pushing the clamp as close to the connector as possible. Then, plug the cable into the device's HDMI port, and insert the cable tie into the clamp, removing all slack, so the HDMI plug cannot come loose. Removing the cable tie from the clamp allows you to unplug the cable. Lifetime Warranty The P568-000-LOCK is backed by a lifetime warranty, ensuring reliability and performance.
