HEAVYBILT LEXINGTON
SELF-LOCKING MAILBOX

Introducing a new concept in Heavybilt Self-Locking Mailboxes: the Lexington. This new model replaces the former Self-Locking Mailbox manufactured by GDM Mailbox, LLC, and offers a heavy cast aluminum door with designer styling, which fits over the front of the mailbox body. This offers superior weather resistance while keeping the same outstanding features of the Heavybilt Self-Locking Mailbox: The self-locking mechanism, letter slot, and 12 gauge heavy duty construction.

• The Lexington is available in six colors.  They are fabricated using modern robotic technology and state-of-the-art tooling.
• Letter slot measures 7 3/4" by 1 1/4"
• Constructed of 12 Gauge High Strength (Certified Premium) Steel ("B-75" Rockwell Hardness)
• Will support between 14,760 and 21,780 lbs. of direct weight.
• Direct door pull against lock tested up to 440 pounds of pressure.
• 3 stage automotive grade finish:
• Black Oxide Undercoat
• Baked on Electro-coat
• Baked on High Strength Polyurethane Powder Coat with UV Protection for life-long beauty.
• Mailbox has a Full-width/Full-Travel heavy duty stainless steel hinge with a stainless steel hinge pin that won't rust.
• Mailbox flag has industrial grade nylon bushing to insure smooth life-long operation, and stainless steel fasteners.
• Optional Key Blanks available for duplications.
• Offered in Plain Door version [right] and with powder coated Eagle Door Plaque [above]

• Important: The Lexington Self-Locking Mailbox is designed to work on a sturdy mailbox post, properly installed to handle a 39 pound mailbox. Any post that is leaning or wobbles in the ground will not be adequate support for proper function of the lock mechanism. We recommend securing any post with well-packed back fill dirt or dry ready-mix concrete, tamped around the base of the post.

How it works

Please note: This is a self-locking mailbox, not a locking mailbox. It functions just like a normal mailbox so far as the USPS is concerned. They do not have to carry a key, nor is the door slot the primary means for mail delivery. It therefore meets requirements by the US Postmaster General for non-locking mailboxes. There is no category in USPS regulations pertaining to “self-locking mailboxes.” Therefore when customers ask, is this a US Postmaster General Approved locking mailbox? ... technically the answer is No, but the mailbox design also is not technically a “locking mailbox.” Here is how the mailbox works:

The key is placed into the lock with the door in the closed position. The key is turned to the right and withdrawn. At this point the door may be opened one time, after which the lock engages, and the mailbox door is locked. When the mail carrier comes around for outgoing mail retrieval and incoming mail delivery, he/she pulls open the door, takes out-going mail, leaves incoming mail, and closes the door. The self-locking mechanism becomes engaged at this point, and remains locked until the homeowner inserts the key, turns it to the left and opens the door. The process is repeated for next day’s mail delivery. 

The letter slot is for backup purposes only. Sometimes we forget to pick up our mail. This prevents the carrier from being inconvenienced because he/she can still deposit mail through the slot. Because the height dimension does not meet USPS specs at 1.75”, this mailbox may not be used with the door permanently in the locked position. However, the slot does save both mail carrier and homeowner inconvenience and delay in receiving mail. Another situation where it comes in handy is when the homeowner is away for a weekend. Rather than making a special trip to the Post Office to file a Hold Mail slip, the carrier can simply deposit incoming mail through the slot on Saturday’s delivery.
