If you are struggling to clean dirt from under vehicles and other equipment, the Pivot Coupler is the accessory you need! Compatible with all STIHL RB pressure washers, this tool is made of brass and steel for durability and corrosion resistance. It adjusts to three different angles to clean hard-to-reach areas and to provide you with more versatility and control. Plus, the Pivot Coupler locks into place with ease, allowing you to work from a standing position instead of bending and reaching.
