Frequently Asked Questions

How long will the aluminum construction on the Salsbury 3504SRU last in outdoor weather conditions?

The high-quality aluminum construction is designed for long-term durability and weather resistance, making it suitable for years of outdoor use in various climates. The sandstone finish also provides additional protection against UV fading and corrosion.

Can the Salsbury 3504SRU be installed on an apartment building or is it only for single-family homes?

The 3504SRU is specifically designed for apartments, condominiums, and commercial buildings with its 4-door configuration allowing multiple tenants to have individual mailbox units. It's an ideal solution for properties that need centralized mail delivery for multiple residents.

What does 'recessed mounted' mean for the Salsbury 3504SRU, and how does it install?

Recessed mounted means the mailbox is installed into the wall rather than protruding outward, creating a flush, integrated appearance. You'll need to have or create an opening in your wall structure where the unit sits, and it requires professional installation or carpentry skills for proper fitting.

Is the USPS lock on the Salsbury 3504SRU secure enough to prevent mail theft?

Yes, the USPS-approved lock meets postal service security standards and is designed to prevent unauthorized access to mail. The lock is integrated into the mailbox design and is the same type trusted by the United States Postal Service for secure mail delivery.

How much space does each individual mailbox door have in the 4-door Salsbury 3504SRU?

Each of the 4 doors provides adequate space for standard mail and small packages, though exact dimensions should be verified with the product specifications. The vertical design maximizes storage capacity while maintaining a compact footprint suitable for buildings with multiple residents.
