3600 Series Front Loading
Horizontal Mailboxes are Adaptable
USA Building Supplies has both standard and custom configurations available of front loading horizontal mailboxes. Standard configurations of USPS 4B+ Approved horizontal mailboxes can be a maximum of seven single high single wide resident doors high (referred to as an "A" door size) and five wide of the "A" size door. Front loading USPS 4B+ compliant horizontal mailbox cannot be wider (more doors across) than it has doors high. The primary purpose for this limitation is the weight of the gate cannot be supported in this type of module configuration. USA Building Supplies offers nine different standard configurations consisting of seven, six, and five "A" doors high and five, four, and three doors wide. Customized horizontal mailboxes can be built within manufacturing and postal restrictions. Different size doors can be built into door arrangements to accommodate tenants who receive larger amounts of mail. An oversize door with a slot can be built into a configuration for outgoing mail. Parcel lockers are another sought after custom option that prospective clients ask for so their residents can receive packages. Two additional considerations should be made before purchasing either standard or custom horizontal mailbox. First, USPS 4B+ compliant mailboxes are approved for replacement purposes only. Second, horizontal mailboxes can only be recessed into a wall. Inquire today about horizontal mailboxes from a USA Building Supplies' expert.
