Are there accessories to the PlexiDor? Yes, there is an awning available, and a sliding track system that makes it easier to attach the security plate. The PlexiDor Awning prevents rain, sun, snow, and wind from entering through a pet door. The awning is made from aluminum with a baked-on finish in white or bronze. There are currently three sizes to choose from: Small: 12″ wide x 8″ deep Medium: 16″ wide x 12″ deep Large / XL: 23 1/4″ wide x 16 5/8″ deep. On this picture, you see the awning outside an electronic PlexiDor. The PlexiDor Sliding Track System is another popular accessory. It’s great for people who attach the security plate often – many use it every evening, or whenever the door is locked, signaling to pets that the pet door is off limits. The Sliding Track system comes with all hardware and mounts to the inner frame in minutes. Then, the security plate slides down the track into place and does not need to be screwed on every time. A flip lock at the top ensures the plate stays in place. The tracks are made of strong, durable aluminum and comes in Silver, White, or Bronze. They are available for door sizes Medium, Large, or Extra Large.
