Letter Lockers

A letter locker is a heavy-duty, USPS-approved locking mailbox built around an anti-fishing design, manufactured by Jayco Industries. Letter lockers cover three main installation types: residential pedestal models, wall mount versions, and high-volume commercial collection boxes. Each letter locker mailbox uses a large incoming slot that drops mail through a rotating hopper or internal chute baffle, putting incoming mail out of arm's reach the moment it's delivered.  Behind the slot sits a locked recipient access door, available in front or rear configurations on most models, secured with a USPS 5-pin cylinder lock as standard. Mail capacity ranges from one to four weeks depending on the model, and every box is made in the USA. Standard, Super, and Supreme variants qualify as USPS-approved mailboxes for residential and commercial delivery, while Arrow Lock builds and wall mount versions also work as a locking letter box once approved by the local Postmaster.

The line splits into seven main variants, from the entry-level Light Duty through the four-week-capacity Supreme, plus heavy-gauge, stainless, and wall mount builds. Capacity, slot size, construction, and outgoing handling differ enough that most buyers narrow their pick from this table. Standard, Super, and Supreme come in front or rear access, with rear access carrying a small upcharge.

The Letter Locker mailbox features that matter most break down into three areas: construction that holds up against weather and prying, security hardware that locks mail away from theft, and mail handling that's easy to live with day to day. Standard models include everything below, with material and security upgrades available across most tiers.

O   Body materials: 14-gauge and 16-gauge electro-galvanized (Galvanneal) steel standard. Optional 10-gauge
      heavy duty steel, aluminum, or #4 brushed stainless steel upgrades. Heavy duty bodies are all-welded. Made in the USA.

O   Powder coat finish: Weather-resistant powder coat in five standard colors: black, white, tan, gray, and bronze.
      Optional extra-protective clear powder coat for extreme climates.

O   USPS approval: Standard, Super, and Supreme are USPS-approved for residential and commercial delivery. Light Duty and
      Wall Mount are USPS-approved with local Postmaster confirmation recommended.

O   Modular installation: Pedestal-style boxes mount to surface-mount or in-ground mailbox posts, sold separately.
      Up to four boxes can share a single post for multi-tenant installs. Wall mount versions surface-mount or recess into walls.

O   Warranty: Conditional lifetime warranty on letter locker mailbox bodies.

O   Standard locking (Level 1): USPS 5-pin cylinder lock with a 3/16" stainless steel hook cam, fitted to the
      locking recipient access door. Two keys included.

O   Anti-fishing protection: Super and Supreme pair a rotating hopper door with internal comb baffles that drop incoming mail
     past arm's reach. Standard and Light Duty rely on a secured access door and locked recipient compartment.

O   Security upgrades: Add a Medeco deadbolt (Level 2), a Claw Lock with pressed dual-plate door (Level 3),
      or both combined (Level 4).

O   Outgoing mail and access: Outgoing mail tray on Standard, Super, and Supreme models. Side-mounted red stainless
      steel flag (standard or optional depending on model). Front or rear recipient access door available on most models.

Most Letter Locker models come in front or rear access. The choice usually has nothing to do with security and everything to do with where the box sits and how you'll retrieve mail. Front access is the default and cheaper of the two; rear access carries a small upcharge but is the safer pick for specific install conditions.

A common rear access pick is the Super Letter Locker (rear access), which keeps the hopper-door anti-fishing design while moving the recipient door to the safer side.

Every Letter Locker ships with Level 1 security as a baseline. The four tiers stack: each one adds a harder lock, a tougher door, or both. Pick the tier that matches the threat in your neighborhood, not the highest available. Over-speccing a Level 4 lock in a quiet suburb is mostly an expense; under-speccing a Level 1 in a known mail-theft area is a real risk.

The default lock on every model. A USPS-style 5-pin tumbler turns a 3/16" stainless steel hook cam that secures the recipient door. Two keys are included. Suitable for low to moderate-risk suburban installs where the main threat is opportunistic fishing rather than targeted prying.

A pick-resistant Medeco mailbox lock paired with a 10-gauge steel door. Medeco is one of the most respected names in lock hardware, with UL-rated cylinders that resist standard picking, bumping, and drilling tools. Choose Level 2 if you want commercial-grade pick resistance without changing the cam mechanism.

A USPS-approved 5-pin tumbler driving a 10-gauge stainless steel "claw" cam, paired with a recipient door pressed from two 14-gauge plates. The claw lock mailbox cam geometry makes prying significantly harder than a standard hook cam. This is the recommended upgrade for known mail-theft neighborhoods.

The highest tier. A Medeco mailbox lock deadbolt and a Claw cam together, behind the pressed dual-plate door. Best for high-crime areas, commercial installations, or sites with a documented theft history.

The base build is a galvanized steel mailbox and it suits most installations. The three upgrades aren't about cosmetics, they're about climate and threat level.

Galvanneal (Standard 14-gauge Steel)

The default galvanized steel mailbox build. Electro-galvanized 14-gauge steel finished in weather-resistant powder coat. It's the best balance of price, durability, and security for the average residential install, and it carries the same lifetime warranty as the upgrades.

Heavy-Duty 10-Gauge Steel

All-welded construction around a 10-gauge body. Considerably thicker than the standard build, with no bolted seams to attack. If you're in a known mail-theft area, the heavy-duty 10-gauge Letter Locker is the practical pick. It's also the right choice for commercial sites where boxes face higher physical wear.

Aluminum

Rust-resistant by default. Aluminum doesn't pit or corrode in salt air or constant moisture, making it the go-to for humid, coastal, or high-rainfall climates.

Stainless Steel

A #4 brushed stainless steel mailbox with full corrosion resistance and a premium look. The stainless steel Letter Locker is the right pick when the box has to look as good as a modern home or storefront, particularly in coastal areas where powder-coated steel can chip and rust over time.

Pedestal-style Letter Lockers don't come with a post. The right pick depends on whether you already have a concrete pad to bolt onto. Surface-mount posts bolt onto an existing concrete surface like a driveway or sidewalk slab. Drill the bolt pattern, set anchors, tighten the pedestal down. Also the easy reuse path if your old mailbox was set in concrete. An in-ground install sets into a fresh hole filled with concrete, the standard for new construction. Plan on a 24 to 30 inch deep hole, a bag or two of concrete mix, and 24 hours of cure time. Both options support up to four Letter Lockers on a single post for duplexes or shared driveways. USPS recommends mounting the mailbox so the slot's lowest edge sits 41" to 45" above the road, and 6" to 8" back from the curb. Wall mount and Arrow Lock variants have Postmaster sign-off recommended.  Browse compatible mailbox posts to match your model.
