11D Mailbox Suite

Centralized mailboxes are one of the best ways to create a safe and efficient system for tenants in your buildings, whether those are business owners or residents. At Postal Supply, we want to make mailing simple, and we can help you do that with our fully recessed, front-loading 11D mailbox suite. These high double-column commercial mailboxes are heavy-duty and high-quality, meaning they meet the necessary USPS requirements while still providing an important service to your building.

At Postal Supply, we have an extensive selection of 11D mailbox suites for you to choose from, including the Florence 4C mailbox. All these 11D mailboxes have a height of 40-3/”and a width of 31-9/16”, and to properly install them, you’ll need a minimum wall depth of 17”. We have multiple options for you to choose from so that you can find the right mailboxes and mailing system that work with your building’s unique needs.
