High-quality Standard Horizontal Mailboxes made in the USA

Durable, Secure, and USPS Approved

Our standard horizontal mailboxes are constructed from heavy-duty aluminum and feature a powder-coated finish for enhanced durability and corrosion resistance. Each unit is USPS-approved, providing a safe and compliant solution for centralized mail delivery in apartments, office buildings, and other multi-tenant commercial properties.

Customizable Options for Every Property

Available in multiple configurations, our standard horizontal mailboxes can be created to meet your specific needs. Choose from a variety of door sizes, colors, and optional features like custom numbering to ensure a perfect fit for your property.

Front and Rear Loading Options

We offer versatile front and rear loading mailboxes to meet the unique needs of your property. With front-loading units, mail carriers can conveniently deposit mail directly from the front, while rear-loading mailboxes allow for secure access from the back—ideal for locations with restricted front access or dedicated mailrooms.

Both options are designed with durability, security, and user convenience in mind, featuring heavy-duty construction and tamper-resistant locks.
