Our front and rear loading horizontal Aluminum 4C Mailboxes or stand-alone parcelHorizontal lockers are designed for both indoor and outdoor use.  All mailbox systems feature a durable powder coated finish which is not only attractive but protects the aluminum from long-term corrosion.  The powder coat finish also resists scratching and vandalism. Our mailbox systems are available in four attractive colors – aluminum, bronze, gold or sandstone. 


Our front and rear loading horizontal Aluminum 4C Mailboxes can also be configured to your needs.  They are available in a one door wide (single column) and two doors wide (double column) configurations.  As per USPS standards, a 4C mailbox system has a minimum of one parcel locker for every ten tenant compartments.  One popular configuration is the “Maximum Height” model that has two fully integrated 15 ½” high parcel lockers combined with twenty standard mailbox doors.  Other configurations can be ordered from 15 Door high units (total height = 55 inches) to a 3 Door high unit (total height = 13 inches). The most popular configurations are Door high units of 15, 13, 11, 9, 7, 5 and 3 units.  Stand-alone and fully integrated parcel lockers are available in both five (17 ¼ inches) and six (19 inches) equivalent standard mailbox door heights.  There is also a compartment equal in height to two standard doors (6 ½ inches) that is used for outgoing mail collection and is clearly identified with “Outgoing Mail.”
