With any new construction, certified mailboxes must be installed properly. Before permanently placing such bulky items, you need to be sure you’ve made the right investment. U.S. Mail Supply’s anodized aluminum and USPS approved front-loading horizontal indoor mailboxes feature twenty tenant boxes with one large parcel compartment, reflecting the high quality, trusted reputation we have built through decades of experience in the postal industry.

Best suited for hotel lobbies, mailrooms, apartment complexes, and college-style dormitories, this front-loading mailbox will have a key to open the mailbox with additional keys for all residents as needed. Installation is an effortless process, as each front-loading mail delivery system arrives pre-assembled. Only needing to be mounted to a wall, these mailboxes are installed with extrusions. A fairly quick setup is complemented by free snap-on trim, delivered with the product courtesy of U.S. Mail Supply.
