4C Mailbox Use and Regulations:

As of 2006, all new construction, new mailbox applications and major renovation sites using centralized wall-mounted USPS mail delivery are required to have a 4C mailbox system. To adhere to USPS installation requirements, your 4C Mailbox should not exceed 67” from the finished floor to the top row of locks, and there must be at least 28” from the finished floor to the bottom of the lowest tenant compartment. An exception can be made and this dimension can be minimized as low as 15” only when the lower compartments are 4C Mailbox parcel lockers.Our 4C horizontal mailboxes are front-loading only (mail carrier access from the front).
