Let man’s best friend come and go as they please with this electronic dog door! Automatically opens when the door senses the dog approaching from an ultrasonic collar. Comes standard with automatic deadbolt locking.

Motor driven vertically-sliding door is activated by MS-4 ultrasonic collar.
Directional sensing system opens the door only when your pet is on a direct approach, not when he is just wandering by or sleeping next to the door.
4-way access control lets you select from In Only, Out Only, Full Access or Closed & Locked.
Wind and weatherproof with airtight seal; automatic deadbolt locking adds a level of security higher than any other pet door.
