Locking Mailbox Inserts

Mailbox Lockboxes offer a simple and inexpensive way to secure your mail by adding a locking mailbox insert to a standard mailbox. Mail-theft is a growing problem that invades your privacy and can cost you countless dollars.

In recent years, Mailbox Lockboxes have become a popular alternative to total mailbox replacement. These locking mailbox inserts meet the needs of many customers who are either happy with their existing mailbox or who would find their current mailbox difficult to replace.

Locking mailbox inserts can be installed in your existing mailbox, or they can be installed in a brand new Post Office approved mailbox. Our lockbox is specifically designed to fit medium size rural style post mount mailboxes.

Furthermore, our locking mailbox insert can be secured inside any mailbox with a minimum 8" wide opening. Many of the high-end cast aluminum mailboxes on the market today can be upgraded to a locking unit with one of our locking mailbox inserts.
