USPS Postal lock setup
For non-residential use, the United States Post Office has an “Arrow Lock,” which can be used with a non-curbside, Fort Knox Mailbox. The benefit is that companies or multiple mailbox-owners can have their incoming and outgoing mail locked up (or safely stored). To be able to use an “Arrow Lock,” you must first obtain special approval from your local post office; not all post offices allow use of the “Arrow Lock. Once you obtain approval, we can sell you a mailbox that is then ready for use with the “Arrow Lock”, and with all hardware included for the installation.
Please note that Fort Knox Mailbox is unable to install the “Arrow Lock” on our mailboxes. Your local post office will install the “Arrow Lock” onto the mailbox once the mailbox is installed.
As important, you will need to add a rear door to your mailbox for most setups. If this use is for an outgoing mailbox only, then only a slot is needed for outgoing mail deposit. Once we drill the holes for the Arrow Lock, the purchase on our mailbox is final—no returns.
