4C Horizontal Mailbox Applications
The United States Postal Service (USPS) has rigid guidelines when it comes to the standards for the construction of these versatile locking commercial 4C mailbox suites. All 4C horizontal mailboxes are extremely rugged and subject to installation requirements for maximum height and distance off the floor.
On October 2006, the USPS-STD-4C was implemented, which applies to all wall mounted commercial mailboxes for centralized mail distribution including those installed in urban and rural settings. Centralized mail delivery systems are highly efficient for mail delivery and collection offering better mail protection and providing easier access for both the tenants and the USPS mail carriers.
USPS Approved 4C Commercial Mailboxes
MailboxWorks offers several types of USPS approved, pre-configured 4C horizontal mailboxes by Auth Florence Manufacturing. You can mix and match 4C cluster mailbox modules to customize your centralized mail delivery system to meet your project needs.
Auth Florence 4C horizontal mailboxes are simple, easy to use and extremely versatile. They undergo stringent security testing by USPS and feature thick, vandal proof reinforced mail collection doors with one-piece extruded hinges that are designed to resist prying. They also include standard heavy-duty cam locks and at least one parcel locker for every ten commercial mailbox compartments.
For security and privacy reasons, and to better comply with accessibility regulations, The MailboxWorks also recommends your horizontal mailbox compartments be sequentially numbered.

4C Mailboxes Surface Mounted
