"Second Quality" Locking Mailbox Insert - You Save $10 !

The inserts we are selling on this page are not first quality.... however... they are perfectly 100% functioning units that might have a "ding" or some paint imperfection that prevents us from selling them as "First Quality". And considering that lockboxes are completely concealed inside your mailbox.... I think these are a great way to save a few bucks. WHILE SUPPLIES LAST. Not many units available.


This locking mailbox insert adds a locking compartment to any ordinary standard mailbox. Constructed from 14 gauge steel with a stainless steel hinge. Two keys included. Mail gets pushed through slot. Slot bent inward to help prevent a hand reaching in to steal your mail.

These are not vaults, but they do protect mail from a casual thief and it will offer an excellent visual deterrent. Once a mail thief sees your lockbox, he'll probably move on to an easier victim.

Do-it-yourself: Attaches inside your existing mailbox by drilling one hole in your mailbox floor and then fastening the lockbox in-place by tightening just one screw (screw included). This special screw uses a lock-nut that cannot be loosened from the underside.

Below we picture the small locking mailbox insert. It is the only one we sell that has a side flag cut-out. It has been our experience that only the small unit needs the cut-out.

Key Blanks: $3.00 each

A locksmith can make duplicate keys using our key blank. When we say locksmith, we don't mean Home Depot. We mean a professional locksmith.
