This authentic OEM replacement hinge plate frame attaches to the handle of a pressure washer and allows the operator to adjust the position of the handle. This way, the operator can get a better angle on whatever it is that they are cleaning and can hold the pressure washer more comfortably. The hinge plate frame attaches to the handle hinge, and as such, it is susceptible to drops and bumps. If an operator accidentally drops their pressure washer gun against a hard surface, the plate frame may break off and be irreparably damaged. If so, a new part will have to be purchased. Switching out a damaged hinge plate frame will require a screwdriver. Be sure to hold onto the two screws removed during disassembly, as they will be needed to attach the new plate frame. This replacement hinge plate frame is compatible with pressure washers made by Generac. As such, this part comes sourced directly from Generac. No additional hardware is included in this shipment. If the two assembly screws are lost, they will need to be bought separately.
