What are Standard USPS Cluster Box Units?

The Salsbury Standard Cluster Mailbox and Regency® Decorative CBU Type I, Type II, Type III, Type IV, Type V, Type VI and Outdoor Parcel Lockers (OPL's) are all licensed and approved by the U. S. Postal Service. Ideal for commercial buildings, multi-family housing units, apartment complexes, government and military bases, schools, colleges and other residential and commercial developments, cluster mailboxes are ultra-durable and provide a secure means of receiving mail and packages. When you install your Cluster Mailbox the local post office will install an "Arrow Lock." This lock is used for the local post master to open the unit and deliver the mail. When the U.S. Postal Service delivers a package to the parcel locker, a parcel locker key is placed in the recipient's mailbox. Once the recipient opens the parcel locker, the key is automatically retained in the lock until it is removed with the USPS control key.

What is Standard USPS-STD-4C?

The United States Postal Service addressed the shape of mailbox compartments and the demand for more secure mail and parcel delivery with a new standard, USPS-STD-4C. This standard replaces the traditional cube style compartments with more flat style compartments as well as incorporates fully integrated or stand-alone parcel locker options into the mailbox. A minimum of one parcel locker is required for every five (5) tenant compartments. Parcel lockers are not required in installation sites with less than five (5) tenant compartments. Salsbury Industries 3700 series 4C standard and custom high security horizontal mailboxes and fully integrated and stand-alone parcel lockers have been USPS approved and meet the specifications of USPS-STD-4C. This standard requires that 4C horizontal mailboxes and parcel lockers be installed in all new construction projects and major remodels effective October 2006.

What is Standard USPS-STD-4B+?

The demand for improved mailbox security prompted the United States Postal Service to develop this standard. This standard requires manufacturers to strengthen and improve the master door (arrow lock compartment) on vertical style apartment house mail receptacles (3500 series) and horizontal style apartment house mail receptacles (3600 series). All Salsbury Industries 3500 and 3600 series mailboxes are USPS approved and in full compliance with the requirements of USPS-STD-4B . These 4B vertical and 4B horizontal mailboxes are approved for replacement and/or retrofit installations effective October 2006. For new construction or major remodels, 4C horizontal mailboxes (3700 series) are required.
