The Freedom They Deserve, and the Security You Expect

Large pets of all energy levels may come and go as they please with this Havahart® Large Aluminum Pet Door. This pet door features a flexible PVC flap with a magnetic energy seal that reduces temperature loss from your pet entering and exiting the door and a lockable steel panel to give you extra peace of mind. And its high-quality aluminum construction ensures a more durable and long-lasting solution than a plastic door.

Simple 3-Step Installation

Install your Large Plastic Dog Door in 3 easy steps:

1. Use the door template to draw an outline of the unit on your door.
2. Drill a starter hole in any corner, and cut along the outline with a jigsaw.

We have a metal exterior door. We bought this and didn't put it in before we moved. Is this a self-framing model? Want to make sure it will work in case we need to order a different one.
