Frequently Asked Questions

Is the Salsbury 3504ARU aluminum mailbox weather-resistant and how long does it typically last?

Yes, the aluminum construction is highly weather-resistant and designed for long-term outdoor durability, typically lasting 10+ years with minimal maintenance. The material naturally resists rust and corrosion, making it ideal for various climate conditions.

Can the Salsbury 3504ARU be installed in a recessed wall opening, or does it need to mount on the surface?

How many residents or units can this 4-door mailbox accommodate?

The 4-door vertical configuration is ideal for small apartment buildings, condominiums, or commercial properties with up to 4 separate mailbox compartments, allowing each unit/resident to have their own secure mail access.

Is the Salsbury 3504ARU USPS approved, and will mail carriers use it?

Yes, the 3504ARU is USPS-approved (4B+ Standard compliant), so mail carriers are required to use it for mail delivery. This approval ensures it meets all postal service specifications for security and accessibility.

Does the Salsbury 3504ARU come with locks for each door, and are replacement keys available?

Yes, each of the 4 doors comes with its own secure lock and master lock system for property manager access. Replacement keys and lock cylinders are available separately from Salsbury Industries if needed.
