Product Details
The recessed mounted 4C horizontal mailboxes are U.S.P.S. approved and manufactured by Salsbury Industries to USPS-STD-4C specifications, making them ideal for apartments, commercial buildings, and residential developments. They are required for new construction and major renovations and suitable for indoor or outdoor use. Constructed of heavy duty aluminum with stainless steel hardware, the doors feature a heavy duty cam lock with a dust/rain shield and come with three keys. Door sizes vary with MB1 doors measuring 3-1/4" H x 13-1/4" W, MB2 doors 6-3/4" H x 13-1/4" W, MB3 doors 10-1/4" H x 13-1/4" W, and MB4 doors 13-3/4" H x 13-1/4" W. U.S.P.S. Standard 4C requires a minimum of one parcel locker of at least 15" H for every five tenant compartments to meet the 1:5 ratio, although smaller parcel lockers can also be added once this ratio is met. The outgoing mail compartment includes a U.S.P.S. master lock access door, installed by the U.S.P.S., which cannot be used for mail distribution, and features a 10-3/4" W x 3/4" H mail slot with a weather protection hood. The mailbox units come with factory installed 3/4" W x 1/4" D trim and a solid rear cover, as well as a 4C horizontal mailbox connector kit with hardware for easy connection of multiple units. ADA height compliant units are available according to ADA compliance guidelines. Salsbury Industries, an ISO 9001:2015 certified company, has been manufacturing these mailboxes since 1936.
