The Mosmatic Wall Boom WAD (61.419) is a dual-arm wall-mounted boom system designed for outdoor wash bays, fleet maintenance areas, and industrial cleaning environments where ceiling installations are not feasible. With two independently rotating arms—5 ft 9 in (lower) and 5 ft 3 in (upper)—this unit provides extended reach and efficient dual-medium functionality. Each arm offers 180° smooth rotation and is supported by a return-to-rest wall bracket for clean, consistent storage.

Ideal for systems using both high and low pressure, the upper boom is recommended for low-pressure applications, such as foam brushes, while the lower boom supports high-pressure spray equipment. The unit is equipped with an insulated high-pressure (HP) hose, handles up to 4000 PSI, and supports operating temperatures up to 250°F. It is compatible with water, oil, and air (pH 3–12) and includes 3/8" NPTF inlets (top and side) with a 3/8" outlet, delivering environmentally friendly, high-performance operation.
