Product Details
Regency decorative cluster boxes manufactured by Salsbury Industries provide USPS access and secure mail and package receiving, designed for commercial developments and residential neighborhoods. The 3300R series is a USPS access cluster box unit (CBU) that includes a matching pedestal, decorative top, and decorative pedestal cover. Constructed of heavy-duty aluminum and stainless steel for durability, these CBUs feature front access through two easy-opening master door panels. They are available with "A" size doors measuring 12-3/4" W x 3-1/4" H, "B" size doors at 12-3/4" W x 5" H, and "C" size doors at 12-3/4" W x 6-3/4" H. Each door has a heavy-duty 5-pin cylinder cam lock with a dust and rain shield, supplied with three keys. One compartment is labeled "Outgoing Mail" and includes a weather protection flap and an 11-3/4" W x 3/4" H mail slot. The unit includes a carrier access door for USPS-installed master lock and features one, two, or four fully integrated parcel lockers available in small (12-3/4" W x 10-1/4" H) and medium (12-3/4" W x 13-3/4" H) sizes. Minor assembly is required. Salsbury Industries is officially licensed and authorized by the U.S. Postal Service to manufacture cluster box units (License # 1CDSEQ-08-B-0026), produces to USPS "F" specifications, and is ISO 9001:2015 certified, having manufactured since 1936. For private access applications such as colleges and military bases where a non-USPS employee delivers mail, master commercial locks (P/N 3375) for the access door and individual parcel lockers should be ordered.
