The Single Hook Leash Holder measures 4.25 inches wide by 7 inches high. The tile is made from a hardhoard and is mounted to a metal rectangle. The hook hangs down from the metal plate in the back and is about 2 1/2 inches from the base. The hook opens about 1 inch. A hanger is attached to the metal plate and is about 1 1/2 inches 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.
