Large Locking Mailbox Insert | Lockable Mailboxes

10.5" wide Locking Mailbox Insert

We sell different size locking mailbox inserts. They all can be seen on our Mailbox Lockbox Main Page. <MORE INFO>

This locking mailbox insert adds a locking compartment to an ordinary standard mailbox that has an opening that is at least 10.5" wide (left to right).

Sturdy construction with 14 gauge steel doors and 16 gauge steel bodies with stainless steel hinges. Two keys included. Mail gets pushed through slot. Slot bent inward to restrict a hand from reaching in to easily 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.

INSTALLATION TIP: It is very important to follow our installation instructions and be sure the threads of the machine bolt we include go downward and stick out under the mailbox floor. Use the "lock-nut" we include to fasten the lockbox in place. Lock-nuts have vinyl threads to prevent anyone from backing the nut off. To loosen that bolt, you would need a key to the lockbox in order to hold the machine bolt head. Otherwise, the bolt/locknut will just spin and spin. Some people mistakenly think the threads go upward. That is wrong. The bolt going upward into the lockbox gets in the way of easily removing your mail.
