Medium Size Locking Mailbox Insert

This is our most popular size. Below are the many mailboxes this lockbox can be adapted to fit.

Locking mailbox inserts add a locking compartment to any ordinary standard mailbox. Constructed from 14 gauge steel with a stainless steel hinge. Custom made heavy duty cam lock with 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 a visual deterrent. Once a mail thief sees your lockbox, he'll probably move on to an easier victim.

Medium Size -
Measures approx 7.5" wide x 5.75" tall x 18.5 " deep.
Slot size: 7.25" wide x 1.5" tall

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 are some pictures of the small mailbox lockbox. The medium size unit is basically the same, except it doesn't have the side flag cut-out (not needed for medium mailboxes). How the medium size works and installs is exactly the same.
