Fort Knox The Vault Series


Beginning size 12″ x 24″ x 23″ at 170 LBS.

Our Vault Series mailboxes came about in the late 90’s. A customer needed to securely lock packages because they were unable to get the mail every day. That led to the Vault Series! Now they are in full production due to high demand. These mailboxes are built like a postal delivery drop off box with a “baffle” to accept packages, but keeping arms and hands out. They are fabricated to stand up in the toughest circumstances. The Vault Mailbox is made to accept a 3″ tall package, while our larger ones will hold a 6″ tall package. There are more specifications below — see which one will work best for you!
