High Tech Pet PX-1 Power Pet Fully Automatic Pet Door offers the freedom that your small pets want with the security that you need. This state-of-the-art pet door opens only with the sensor from the coordinating High Tech Pet Microsonic Collar. As your pet approaches, the door quickly and quietly opens upwards, meaning pets no longer have to push through swinging doors. The automatic deadlock keeps it extra-secure, and the custom settings give you total control. Can be installed in a traditional door or wall. Power Pet Doors are hermetically sealed and completely wind proof.
