12 Door Horizontal Mailbox Unit for Offices and Apartment Buildings

U.S. Mail Supply has reputably fulfilled orders to fit the needs of large apartment complexes and individual customers looking for intelligent mail delivery solutions for years. For our 12 door mailboxes, we typically receive orders in a plural quantity because contractors or building owners of commercial properties want to install multiple products in quick succession.

Before you invest in our 12 door mailbox unit, keep in mind it is USPS certified as an indoor product only and should not be installed outside where it can be mercilessly exposed to the elements. The most common location for this 1400 Series Horizontal mailbox is a first floor lobby with easy access for tenants or workers for the exchange of mail.

For bulk orders, we recommend you consider our engraving services or the standard plastic number slots to help you organize your system once it’s installed. Conducting your engraving with US Mail Supply helps eliminate third-party engravers who are not always familiar with our products and their finishes.

Contact mailbox dealers at U.S. Mail Supply today if you’re interested in our custom engraving, always completed on-site for installation.
Make sure to choose the RIGHT mailbox.

Don't worry, we can help you figure out what's best and most cost efficient for your space. A representative at U.S. Mail Supply will help you figure out what is required for USPS or private delivery, the number of units you need and any information required for installation.
