Locking Mailbox Wall Mount 14.3 x 4.1 x 11.8 in Black - Secure Mailbox

Our review of the Locking Mailbox Wall Mount for outside use finds it best suited to homeowners who want a neat, secure place for everyday letters and small parcels. The single biggest reason to buy is its balance of practical capacity and keyed security: the exterior size fits a wide mail slot while the keyed lock keeps deliveries private. Installation is straightforward and the black finish is unobtrusive, making this a sensible choice for front doors and fence mounting where durability and a tidy look matter.

Key Features

• Durable Construction: The mailbox uses high-quality materials designed to stand up to outdoor elements and daily use.
• Secure Key Lock: A keyed locking mechanism keeps letters and small packages secure from casual tampering.
• Spacious Interior: The inside storage of 12.25 x 10 x 3.7 in fits multiple envelopes, magazines and some small parcels without folding them.
• Sleek Design: The black, modern look complements many home exteriors and improves curb appeal without being flashy.
• Number Stickers Included: Three sets of reflective sticker mailbox numbers let you label or reassign the mailbox easily for shared runs.
• Easy Installation: Clear instructions and a wall-mount design make attachment to a door or fence straightforward for most DIYers.

Who It's For

This mailbox is a good match for homeowners, renters with permission to mount to an exterior, and small-property managers who need a reliable, keyed mailbox for routine deliveries. It works well where medium capacity and weather resistance are the priorities rather than heavy-duty package storage.

People who routinely receive large parcels, need high-security locking bolts, or want premium marine-grade metal would be better served by a larger parcel locker or a mailbox with reinforced locks. Those users should look elsewhere for extra-large capacity or tamper-resistant commercial designs.
