Stacked Rack for 7 or More

If space is an issue and you have 5 or more mailboxes, then our custom steel stacked racks are the answer. Double stacking is also a great space saver when you have little room. With this style, you can mount up to 18 mailboxes on a single rack. These racks are completely welded, and custom set up for any Fort Knox Mailbox. You can also mount other mailboxes. The posts will support our heavy mailboxes, and they don’t have to be the same model. All of our racks are custom made of our fabricated 3/16″ thick channel and 11-gauge steel posts.
