A: Yes, you can install the PlexiDor Wall Unit dog door into a cement block wall. The only thing to be careful with before starting is to check both sides of the wall to avoid electrical outlets and plumbing. An exterior visual check is not a guarantee. We recommend you cut a 4 inch by 4 inch test hole through the dry wall first to take a peek in the wall to be sure you don't have any surprises getting in the way. We have a video on our website to show an example of an install in a cement block wall. Here is that link: https://plexidors.com/videos/block-wall-installation-of-plexidor-dog-door/

A: Sliding Track: Features and Benefits PlexiDor dog doors size large, medium, and extra large are delivered with a steel security plate that screws onto the pet door frame. The plate is a great tool for securing the home, and for signaling to pets that the door is locked. Using the sliding tracks, it takes seconds to mount the plate. Simply attach the left and right tracks to the interior frame, and slide the steel security plate down the track into place. The tracks attach to the dog door’s interior frame using just a screw driver, and the security plate slides down to its optimal position. Secure the plate with the handy flip lock feature and you’re finished. The tracks are made of strong and durable aluminum, and they’re available in silver, white, or bronze in sizes Medium - 40lbs | Large - 100lbs | Large Plus - 150lbs | XLarge - 220lbs Hardware for track installation is included, but not the security plate itself.
