The tile is made from a hardboard and is mounted to a metal rectangle. The hook hangs down from the metal plate in the back and is about 2.5" from the base. The hook opens about 1". A hanger is attached to the metal plate and is about 1.5" long. Lots of room to hang up using a screw or paneling nail. Great for the home or office to hold keys, leashes or just about anything.
