A Pendulum Electric Window Marine Wiper Arm is characterized by its unique pendulum-style design, providing efficient and smooth windshield wiping in marine environments. The pendulum mechanism allows the wiper arm to pivot around a central point, adapting to the curvature of the windshield. The electric component indicates that it is powered by an electric motor, offering controlled and adjustable wiping speeds. These wiper arms are typically constructed from durable materials such as stainless steel or aluminum, ensuring resistance to corrosion in marine conditions. The pendulum design enhances the flexibility and coverage of the wiper, making it suitable for various boat and ship applications.
