Our Cluster Mailbox Brands

Short for cluster box unit, a CBU is a mailbox consisting of individually locked mailbox compartments and one or two parcel lockers. Our USPS-approved cluster mailboxes from Florence Corporation and Salsbury Industries are some of our best sellers. Let’s take a closer look at each.

Florence Corporation

Headquartered in Manhattan, KS, Florence Corporation has led the industry in producing centralized mail delivery units for USPS use since 1934.

Our Florence cluster box units are available as pedestal mailboxes and recessed mailboxes, and you can get either in the following esthetically pleasing colors: sandstone, bronze, black, and gray. Whatever options you choose, the cluster box units will have a powder-coat finish that protects the stainless steel from weather and scratches.

Whether you want decorative mailbox posts for your luxury development or an extra-secure option for a property in a rougher part of town, we have you covered. We’re one of the few online Florence distributors that carry the brand’s Vigilant High-Security cluster designed for areas high in theft or vandalism.

And the best part? Florence provides a five-year limited product warranty on all items.
