Product Details
Minimal design. Proven aluminum construction.
The Aluma Modern Mailbox – Smooth Post Base offers a simplified take on our original Aluma Modern design. This variation features smooth 2.5” x 2.5” black aluminum end posts paired with white panel infill, creating a cleaner, more minimal profile compared to the original 3” x 3” vertically-lined post design.
This is a design alternative, not an upgrade—built with the same all-aluminum construction, durability, and everyday function as the original.
Designed with a front-facing, USPS-preferred orientation and a modern front-opening mailbox, it comfortably accommodates daily mail, padded envelopes, and small package deliveries.
