Large Payment Box — Built to Protect More Payments 
12" x 12" x 23" @ 96 LBS.

Our Payment Boxes have the same extreme security features as our Small and Large Standard mailboxes. The Payment Box keeps your payments or keys safe, using a small 3/4" slot to allow for keys and envelopes only. Made from 1/4″ steel with 3/16″ reinforced doors to keep your items secure.

Payment boxes come in all mailbox sizes and can be custom adjusted.  Please call for pricing with custom sizes or multiple quantities: (800) 206-8067 or email us at paymentboxes@fortknoxmailbox.com 

How It Works

  1. The payments, envelopes or keys are dropped into the top slot (11.5” W x .75” H).
  2. Items drop into the locked compartment — only you have the key.

Additional details:

  • The body of the Payment Box has an overhang to protect against rain and vandalism.
  • The 3/16" door is secured with a 7-pin tubular pick-proof lock (upgradable).  The door is also re-enforced and recessed, which is VERY important to eliminate prying. 
  • Pre-drilled on the bottom (4 holes, 6 ¾” apart) to fit Small Posts, or mountable on existing posts/surfaces.
  • Finished with thick powder coating inside and out for durability.
