The 28” tall rocker brush shares most of the Wash Works product features such as Color Skinz™ structure wrap and built-in utility chases. However this simplistic design leaves nothing to chance, everything is exposed and easily accessed. Quick hit bulkhead utility connections are provided for water, and electric drive or hydraulic drive, which make utility connections speedy and professional. 4” brush height adjustment provides a perfect match to differing guide rail clearances. A shock and spring provide constant side pressure. Upgrade to air cylinder controls for adjustable pressure and retract capability. Available with C-channel Foam, Composite Core Foam or Cotton Cloth™.
