In 1986, we set out to build the ultimate pet door—and the Power Pet Door was born. Refined through decades of research, our patented design quietly lifts a lightweight panel, then gently lowers it with brake-assisted gravity to keep pets safe. In 2006, we introduced the PX series with a rugged ABS shell and Bob Schilken’s groundbreaking ultrasonic detection, which opens only when your pet’s collar approaches directly—no false triggers.

Featured on TV shows like I Want That, Don’t Sweat It, and House Detective, the PX series is praised for its reliability, affordability, and sleek look. It’s available in two sizes—Medium (up to 30 lbs.) and Large (up to 90 lbs.)—and can be easily installed in a wall with our optional tunnel. Despite imitators, there’s still nothing like the genuine Power Pet Door!

All High Tech Pet Doors can be installed in almost any Wall, Door or Patio Sliding Door.
