The PlexiDor sliding track accessory is easy to install. There are screws provided with the tracks, and you just screw the tracks to the holes where you would normally attach the security plate. You won’t need any additional hardware, just a Phillips-head screwdriver.
Once you’ve screwed the tracks to the frame, remove the machine screws and nylon washers from the security plate, so it can slide down the tracks. Secure the cover with the flip lock.
