Super Letter Locker, Shown in White

The Super Size Letter Locker Locking Mailbox is larger than the Letter Locker Standard yet smaller than the Supreme. It has the same unique security features not found on other mailboxes - providing extra protection. It's made from heavy-gauge powder-coated Steel with a total weight of 58 lbs.

Options include extra-heavy duty 10 ga. Steel models at weighing in at 80 lbs., dual access including rear door, and all-Stainless-Steel models. Locking options include a Medeco lock and/or the unique LetterLocker CLAW mechanism, which makes your LetterLocker virtually impenetrable.

Letter Locker Color Choices

The LetterLocker standard Cam Lock is made of 3/16" steel. In this interior view, it's shown engaging the LetterLocker Mailbox door - very difficult to even get to, much less pry open.

Choices include the standard Cam Lock which is strong enough for most situations. Upgrades include The Claw, or The Claw plus Medeco Deadbolt

Interior view of the locked Claw. Notice the five locking points (red) two of which are at each edge of the door. With the combined strength of the door and The Claw, prying your mailbox open with a crowbar is a virtual impossibility.

Letter Locker's line of mailboxes and other custom products are proudly manufactured right here in the United States of America. Manufacturing takes place in their 17,000 square foot, state-of-the-art facility located in the Southern California High Desert town of Apple Valley.

The Letter Locker design was patented in 1994 and approved by the U.S. Postal Service pursuant to USPS Standard 7, Mailboxes, City and Rural Curbside. Due to the Letter Locker's exceptional design, it is no coincidence that the published USPS specifications for locking mailboxes uncannily resembles the Letter Locker.

Manufacturing the Letter Locker locally in the USA enables us to maintain a large volume of inventory while providing you with the option to customize your product. If you need an unusual size, specific shape, color or design, their fabricators will build it.

Most Letter Locker products ship within 3-5 business days, some custom and commercial items can take up to 3 or 4 weeks to ship. Orders under 75 lbs generally ship via UPS from Apple Valley, CA. Larger orders crated or on a pallet via common carrier. Time in transit generally takes between 5-7 business days, but depends on the destination.
