This is the replacement locking mailbox for the Secure Logic Mail Vault item # 20322.

After searching we found a great replacement for the Mail Vault Secure Logic Locking Mailbox. Made in the USA this locking mailbox has both the security needed to fill the shoes of the Mail Vault and combination keypad which made the Secure Mail Vault so popular.  Making it even better than the Secure Mail Vault was another goal and it was done with two aspect. First, we give you the option to having a key lock, or picking the option with the combination lock.  Second, the mail slot is no longer just a simple drop slot. It has been upgraded with a hopper style drop door. This means when the drop door is opened it closes off the throat of the drop slot and makes it very difficult to phish items out. 

The dimensions are 15" high x 10-5/8" wide x 21" deep, which means your mailbox will easily hold a week or two of mail. The incoming mail hopper door is 3 1/2" high by 10" wide  by 9" deep.

The push button lock requires no batteries.  It works in direct weather, both heat, cold or rain. The key lock option works equally well in all weather conditions and includes 3 keys. 

The incoming mail slot works like a hopper door much like you may have used when dropping mail at your local US Post Office. The mail slot drop opening is 3.5" high by 10” wide and easily accepts envelopes, magazines, small packages, or a box of personal checks.  There is not an outgoing mail shelf, so it accepts larger items. The option for the flag kit will add a outgoing mail flag as well as a clip for out going mail. The clip will be located on the inside of the drop hopper door. When the postal carrier sees the flag is up and mail has been clipped on the inside of the drop door it can be taken by the postal carrier. Made in the USA. USPS Approved.

We couldn't believe how fast it got here. Seems whoever designed the mail box thought it all out well. Installed easily with all the tools and instructions provided.

Many of our neighbors liked it also. Not promising anything, but you may get a few orders.

Thank you again.

"My wife and I ordered one of your boxes last summer, and so did the Bradbury’s across the street. Since then our street has had two mail thefts. One, was another neighbor that turned out bad, they tapped his accounts. Two houses on the street didn’t get touched, ours and the Bradbury’s.
