Retrofit Community Mailboxes - USPS Approved for Remodel or Replacement Use

Replacement Mailboxes for Renovations and Retrofits

In many cases, property managers and owners need to replace older USPS-approved mailboxes, such as 4B horizontal and vertical mailboxes, with units that match the same specifications. Due to updated requirement USPS put into place in 2006, all new construction projects must be equipped with mailboxes that meet the 4C standard. With this new requirement in place, there is still provision to use 4B mailboxes, provided that the mailbox housing or wall opening does not change. For this reason, we encourage customers to reach out to their local post office before purchasing replacement 4B horizontal or vertical mailboxes.

Mailboxes for Contractors and Developers

Mailboxes for contractors and developers include cluster mailboxes, 4C horizontal mailboxes, and multi-unit mailboxes. These typically fall into two categories: retrofit or replacement mailboxes, and mailboxes for new construction. If your project involves a new build rather than a renovation, the new construction page covers the right options.

Our contractor mailboxes are made by quality brands like Florence Corp., Salsbury Industries, Whitehall, Gaines, and Imperial. If you need a custom, best-price quote for your next project, fill out our Quote Request Form and one of our product experts will be in touch quickly.
