15 Door Horizontal Mailboxes for Office Buildings and Apartment Complexes

Brookfield, Wisconsin’s premiere mailbox supplier constructs high-grade products for optimal use, including this 15 door unit. It comes standard with pre-set size mailboxes, including the tenant compartments, collection slot, and larger parcel compartments. Your mailbox is protected by an anodized aluminum finish. This metal coat reassures your tenants’ mail will not be damaged while it is secured in our 1400 Series horizontal mailbox.

If you’re interested in having a name or title engraved on your compartments, our professionals offer customization services to help personalize your product. On each of your doors, you can have up to twelve characters per two lines in a standard USPS US Black text to help make organizing and sorting easier. If you’re a business or establishment experiencing high turnover, we recommend a simple number of engraving to help foster a sense of community in your ever-changing workplace. Interested in something less permanent? Clear plastic number slots provide an equally effective approach to labeling your doors but offer you the flexibility to switch things around in the future or give your mailbox a simpler aesthetic.
