Extra Large Door Mount Plexidor Pet Doors

I’ve done some research for you to provide you with the best pet door for our cold Canadian climate to allow you the comfort of no cold drafts and the maintenance free design will leave you satisfied on your Plexidor decision for a very long time and this big pet door is virtually the same as the Bite Guard Kennel line only with the same options for residential use.

If you’re looking for a pet door that can mount on an exterior door, you’re looking at the right page but if you are looking for a wall mount then click here, or glass mounted click here

I frequently state that I’m a big fan of Plexidor pet doors, and for a good reason – those things are built tough, versatile, they save you money on energy bills and look like they belong on your door and are built for the climate here in Canada.

I recently had a customer sum it up this way,” The mud flap pet door they used to have was like a Kia model but my new Plexidor is the Cadillac of pet doors, I love it.”

This door units frame out a door that is 1 3/4. This is the standard thickness of an exterior door in the United States and Canada on most of the rest of the developed world.

The frame of the Extra Large Plexidor will protect your pet from the cut-out edges of the door. There is no need to ‘frame out’ the hole as the Plexidor comes with all you need to finish it out professionally in either of the 3 fashionable colors.

The Plexidor can be installed in any type of house door, wood, steel, fiberglass, hollow core, etc (if you have french doors contact me to see if you can use your french door or if you will need to install a different door slab or glass conversion model).

Security Plate Sliding Tracks

The PlexiDor security plate is a great tool for securing the home, and for signalling to pets that the pet door is closed. The PlexiDor sliding tracks with flip lock makes mounting the security plate a breeze.

The tracks attach to the dog door’s interior frame, and the security plate slides down to its optimal position. Fasten the plate with the handy flip lock, and it’s done.

The PlexiDor sliding tracks are made of strong and durable aluminum that matches the pet door frame. They are available in silver, white, or bronze, in sizes medium, large, or extra large.

Hardware for track installation is included, but not the security plate itself. The plate is delivered with the dog door.

The smallest door does not have a security plate, because it’s too small for a person to get through.
