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 The key is turned to the right and withdrawn.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.
