Kennel doors are built for industrial use. Locking covers are not included but can be purchased separately. They come with no frames to finish out the interior of a hollow core door or the insulation layer of a wall. They can be very loud. They do last a long time though, and some like the Gun Dog doors are chew proof. The Endura door is not chew proof, but has an extremely long lasting flap in terms of wear and tear.
