Ideal VIP patio pet doors are made for vinyl sliding doors with a track width that falls between 1 1/2" and 1 3/4", such as many styles made by Pella or Andersen.
If you want a vinyl patio dog door that can stand up to extreme temperatures take a close look at Ideal's VIP models. They feature energy-efficient, double pane, low-e glass as well as an energy-saving Lexan Multi-Flex flap. And, unlike many other brands of vinyl patio dog doors, the Ideal VIP models include a locking kit that utilizes the existing lock on your sliding glass door.
Note: If you live in a region with a mild climate check out the lower-priced, single-pane Vinyl Patio Pet Door by Ideal.
