Surface Mount 4C Horizontal Mailboxes for Private Delivery

Retrofit situations often require quick solutions without major construction. Surface-mounted units attach directly to existing walls, making them ideal for buildings switching from individual mailboxes or using private delivery services instead of USPS. The trade-off is a visible protrusion into hallways, but installation is straightforward, and units can be relocated if building layouts change.

Assembly is required, so factor in setup time and costs. These work well for converted buildings, temporary housing, or properties where recessed installation isn't feasible.

Frequently Asked Questions

Can surface-mounted units be used for USPS delivery?

No. Surface-mounted and free-standing (Depot-style) 4C mailboxes are designed for private delivery systems only. For USPS delivery, only recessed 4C mailboxes are fully USPS-approved and equipped with the required postal master lock.

How far do these units extend from the wall?

Most surface-mounted units project 6–8 inches into the hallway. Always measure your corridor width and ensure ADA clearance before installation.

Can these units be relocated after installation?

Yes, that’s one of their main benefits. You can remove and reinstall them with minimal wall patching if layouts change.

What tools or setup are required for installation?

A level surface, wall anchors, and mounting hardware are typically included. Basic tools like a drill and screwdriver are all you need — no special trades required.

What finishes are available for surface-mounted units?

Most models come in multiple powder-coated finishes (bronze, aluminum, sandstone, black, and white) to match interior or exterior design themes.
