Made entirely of aluminum, U.S.P.S. approved 4350 mail chests feature both a front and rear access locking door. Mail is deposited through a non-locking access panel on the front. Each unit includes an outgoing mail tray, a lock with two keys on each door (keyed alike) and an adjustable red signal flag. Units are available in a black, green, silver or white powder coated finish. Mail chests can be mounted on the optional bolt mounted or in-ground mounted aluminum pedestals or a base of your choice. Order pedestals separately. Multiple mail chests can also be mounted on heavy duty aluminum spreaders and attached to any of the pedestals or can be mounted in columns, masonry or walls. Non-locking thumb latches are available as an option upon request (installed at factory). Mail chests are approved for U.S.P.S. curbside mail delivery. Master postal lock not required.
