Provide a stylish yet secure alternative to the standard USPS Cluster Box Units and add appeal to new developments! These high-security, decorative CBUs are available in black, bronze, green, grey and white color options. Purchase new horizontal 13-door units or update existing ones with these new separate bases and tops. Powder-coated aluminum construction adds to overall durability. Simple to install, this unit includes two parcel locks and 13 mail doors. This Cluster Box is not Postal approved-ask your Carrier if they will deliver.
