Product Details
The recessed mounted 4C horizontal mailboxes are U.S.P.S. approved and manufactured by Salsbury Industries to USPS-STD-4C specifications, designed for apartments, commercial buildings, and residential developments, and are suitable for both indoor and 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 include three keys. Door dimensions vary by model: MB1 doors measure 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. Per USPS Standard 4C requirements, a minimum of one parcel locker with dimensions of at least 15" H must be provided for every five tenant compartments; once this ratio is met, smaller parcel lockers may be added. The outgoing mail compartment includes a U.S.P.S. master lock access door installed by the U.S.P.S., a 10-3/4" W x 3/4" H mail slot with a weather protection hood, and cannot be used for mail distribution.
