Seeking signal perfection and reliability from your HDMI cable? The Kaiser HDMI Connector Lock Adapter has been designed to securely connect your Kaiser HDMI Cables or Wall Plates to your appliances. Once fitted, it prevents accidental removal or disconnection. It" easy to install, and one connector lock and one hex nut is supplied. The Kaiser HDMI Connector Lock Adapter is manufactured from a high quality thermoplastic polymer which, when warm, easily slips over the HDMI connector and forms a tight fit as it cools down. A built-in thumbscrew then allows the cable to be secured to one of our HDMI face plates or a suitably equipped HDMI device.
