Stacked Rack for 5 or More

If space is an issue and you need to have 5 or more mailboxes, then our custom steel stacked Racks are made for just that. Especially if you are tight with space, double stacking is a great space saver. With this style of Rack, you can mount up to 18 mailboxes on a single rack. These racks are completely welded and custom set up for whatever Fort Knox Mailbox you want to attach. Yes, you can mount other mailboxes too. The posts are made to support our heavy mailboxes, and they don’t all have to be the same model as well. All of our racks are custom made out of our fabricated 3/16″ thick channel and 11 gauge steel posts.
