Engineered for performance, value and extreme reliability, Power Pet doors are motor driven and activated by a tiny ultrasonic collar. Other electronic pet doors merely unlock a hinged panel, requiring your pet to push it open. That's something that a lot of pets don't like to do. Patented Power Pet doors open completely under their own power. They feature a translucent door panel made of a new super-strength, bulletproof resin. When your pet approaches, the air-tight panel quickly and quietly powers upward disappearing into the stylish housing. Because the panel moves up and down and does not swing out, it can mounted in hermetically sealed grooves for air-tight closure. This mounting arrangement makes it impossible for an intruder to kick it out. The result is the most secure pet door against intruders and stray animals. Your pets are empowered to come and go as they please while their animal friends are politely asked to stay out. Panel Size: 12.38 in. x 16 in. for pets up to 100 lbs.
