The Schmitt & Ongaro Marine Deluxe Adjustable Pantograph Arm (part number 33670) is designed for marine applications requiring a robust and adjustable wiper arm. Constructed from powder-coated 304 stainless steel, it offers enhanced durability and corrosion resistance in harsh marine environments. The arm incorporates a heavy-duty stainless steel spring to maintain consistent blade pressure for effective clearing. It is engineered with a 5/8-inch shaft, allowing for direct replacement of many competitive arms on existing heavy-duty wiper motors.
