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, and required for new construction and major renovations. Suitable for indoor or outdoor use, they are constructed of heavy-duty aluminum with stainless steel hardware. Doors feature a heavy-duty cam lock with a dust/rain shield and come with three keys. Door sizes vary by mailbox type: MB1 doors measure 3-1/4" H x 13-1/4" W, MB2 doors are 6-3/4" H x 13-1/4" W, MB3 doors are 10-1/4" H x 13-1/4" W, and MB4 doors are 13-3/4" H x 13-1/4" W. The U.S.P.S. Standard 4C requires a minimum of one parcel locker, at least 15" H, for every five tenant compartments, with smaller parcel lockers allowed once this ratio is met. The outgoing mail compartment or carrier access door includes a U.S.P.S. master lock access installed by the U.S.P.S. and cannot be used for mail distribution; it has a 10-3/4" W x 3/4" H mail slot with a weather protection hood. The units include factory-installed 3/4" W x 1/4" D trim, a solid rear cover, and a 4C horizontal mailbox connector kit with hardware for connecting multiple recessed mounted 4C horizontal mailbox units. ADA height compliant units are available in accordance with ADA compliance guidelines. Salsbury Industries is an ISO 9001:2015 certified company with a manufacturing history dating back to 1936. The product includes warranty terms consistent with Salsbury Industries’ standards.
