The Mosmatic Wall Boom WAD (61.439) is a dual-arm, wall-mounted boom designed for demanding cleaning applications in outdoor wash bays, fleet service stations, and industrial environments where ceiling mounts aren’t an option. With boom lengths of 6 ft 9 in (lower) and 6 ft 3 in (upper), this unit provides extended coverage and flexible operation, featuring 180° smooth rotation on each arm.

Equipped with a return-to-rest wall bracket, this boom system ensures tidy and efficient storage. For dual-pressure applications, it is recommended to use the upper boom for low-pressure tasks, such as foam brushes, and the lower boom for high-pressure rinsing. The system includes a rugged insulated high-pressure (HP) hose, handles up to 4000 PSI, and withstands 250°F. Compatible with water, oil, and air across a pH range of 3–12, the unit also features 3/8" NPTF inlets (top and side) and a 3/8" outlet.
