10-Door High Suite (37 1/4″H) Compartments – (4 to 18 USPS Approved Mailboxes)

Once the USPS standard for 4C mailboxes was updated in 2006, the biggest improvements made were to the door size and overall security of the mailbox. The larger size allows for larger envelopes and magazines to remain flat and unbent. The mailboxes also have stricter and thorough lock designs for optimized theft protection.
