Superior Strength * High Security * Exceptional Durability

WE GUARANTEE THE LOWEST PRICES ON CLUSTER MAILBOXES! High security, standard cluster box units (CBU’s) are made of heavy duty aluminum and preconfigured with locked compartments, parcel lockers, and a secure outgoing slot for mail collection. Each Florence and Salsbury pedestal mailbox on our site is USPS APPROVED and available in 4, 8, 12, 13 and 16 door configurations ONLY. If these do not exactly match the number of tenant doors needed, purchase the next size up and there will be extra doors that can be left vacant or used in the future if necessary.
