Durable Aluminum Construction for Lasting Use

Built entirely from aluminum, the 3503ASU is designed to withstand the elements and daily use. The powder-coated finish comes in a variety of colors (aluminum, brass, bronze, sandstone, and green) to complement your building's aesthetics.

Individual Compartments for Organized Mail Delivery

This mailbox boasts three individual compartments, each with ample space to accommodate standard-sized envelopes, magazines, and small packages. The individual compartments (5-1/2" W x 16-1/4" H x 6-3/4" D) provide residents or tenants with a secure space for their mail, reducing the risk of mailbox theft or misdelivery.

Easy Installation and Access Control

The 3 Door Mailbox is surface-mounted, meaning it installs directly onto a wall using mounting hardware (not included). This simplifies installation for both new construction and retrofitting existing mail delivery systems. Each compartment features a 5-pin cylinder cam lock with two keys, providing residents with secure access to their mail.
