Our extra large heavy duty 1/4” thick steel mailbox can hold up to the most severe abuse. The drop opening is 1-3/4” high by 11-1/2” wide mail slot which will allow large envelopes to easily drop into the locked secure receptacle. This high security mailbox is USPS approved and works as a High Security Payment Dropbox as well as a mailbox. 

There are three lock options to keep your mail secure. The first lock option is a 7 pin tubular lock, the second lock is a high security Medeco lock and the third option is our most secure, the vault lock. The vault lock acts just like a vault so when the Medeco cam is turned to the locked position is also turns 2 large bolts which secure the door, much like a safe. 

There are two post options. The in ground post must be secured in the ground with cement and the surface mounted post has a flat plate on the bottom so it can be secured to most any hard level surface like a sidewalk or driveway. Pre drilled holes also allow you to secure to your existing post or hard surface.
