14 Door Horizontal Mailboxes for Condos, Apartments and Offices

When you have worked in the mail delivery service industry as long as US Mail Supply, you discover and understand the needs of tenants and residents who have specific requirements for mailboxes in order to meet their needs. We took it upon ourselves to make sure we have a product to meet this high demand of customizable mailboxes. As an owner or operator of residential and commercial properties, this mailbox offers large enough compartments to hold more than average size parcel.

After a conversation with mail delivery professionals, the final step is to determine if your building’s wall or location for the potential mailbox has the appropriate depth for installation. If so, the anodized aluminum finished 13 usable door delivery systems will be perfect. Other than color and security, U.S. Supply can deliver the snap-on trim kit as a free-of-charge addition to your purchase. This is optional, but adds another stylistic element to your mailroom. The trim is available upon request.

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.
