These heavy duty wiper arms are designed for an easy, direct connection to 1/2" drum wiper motors. Unlike other similar wiper arms, this wiper arm does not need a pantograph adapter to connect to the wiper motor to make installation even easier. This carbon steel wiper arm is designed with an adjustable length and has a pantograph sweep pattern. The arm comes with a wet kit for easy installation of washer tubing and nozzles if necessary.
