Lockboxes add a locking compartment to any ordinary standard mailbox. Constructed from 14 guage steel with a stainless steel hinge. Two keys included. Mail gets pushed through the tapered slot. There is a flap on the backside of the door to restrict a hand from reaching in to steal your mail. Not a vault, but an excellent deterrent. Lockbox available in black only.
