  • Patent number: 7931189
    Abstract: A retrofit mailbox security kit includes a binding strap conformable to an interior surface of a mailbox and a hingeably attached security door. A security tab is rigidly attached to the binding strap. The security door in the closed position and the security tab form a mail insertion aperture extending substantially a width of the mailbox. A lock assembly coupled to the security door can restrain the security door in a closed position. The binding strap may be adhered to the interior surface of the mailbox with rivets or with two-sided adhesive tape. The two-sided adhesive tape may be covered with a removably adhered protective film accessible through a clearance aperture in the binding strap to enable the binding strap to be rigidly attached to the interior surface of the mailbox.
