Overview / What Is W50 Pantograph Arm
The W50 Pantograph Arm is a dual-pivot wiper arm used in marine applications to provide a wide and balanced wiping motion. This particular model is adjustable between 1041mm and 1193mm (41 to 47 inches), which makes it suitable for large windshields commonly found on offshore vessels and larger yachts.
It is crafted from marine-grade stainless steel or electropolished for maximum corrosion resistance. The dual-arm configuration provides balanced movement and ensures that the wiper blade maintains contact with the glass surface at all points of its sweep. The pantograph design, unlike single pivot arms, keeps the blade in a vertical position through the full sweep arc — essential for wide, panoramic windshields.
Why Pantograph Arms Outperform Traditional Wiper Arms
The primary advantage of pantograph arms like the W50 is their consistent wiping coverage. Because they are connected at two points — the motor pivot and a secondary sliding pivot — they prevent the wiper blade from shifting sideways during motion. This allows for uniform glass contact and minimizes streaking, a crucial feature during poor visibility conditions.
The W50 pantograph arm also provides added durability due to its dual-support structure. With fewer vibration points and higher resistance to external forces like wind drag, it extends the service life of both the arm and the wiper motor.
How to Install W50 Pantograph Arm
Installing the W50 pantograph arm for marine use is straightforward when done correctly. Follow this simplified guide:
- Disconnect power to the wiper system before beginning installation.
- Locate the motor drive post and secondary arm anchor point.
- Attach the base pivot of the pantograph arm to the motor shaft using a compatible spline or taper lock.
- Secure the secondary arm to the auxiliary anchor point provided by the pantograph system bracket.
- Adjust the arm length to fit the blade sweep angle required for your windshield dimensions.
- Test the sweep range manually to ensure no obstruction or excess tension before powering the system.
Using original components and checking torque settings ensures your installation is seaworthy. Refer to OEM instructions or hire a certified marine technician if unsure.
Maintenance Tips
Maintaining the W50 Pantograph Arm ensures reliable performance and extends its service life. Here are key W50 pantograph arm maintenance tips every boat owner should follow:
- Flush with fresh water: Rinse the arm and pivot points after each saltwater outing to prevent corrosion buildup.
- Check fasteners: Inspect bolts and spline joints monthly for loosening due to vibration or temperature change.
- Lubricate pivot points: Use silicone-based marine lubricant to ensure smooth and noise-free operation.
- Inspect for fatigue: Look for signs of metal fatigue, especially around the anchor points and articulation joints.
By following these practices, your pantograph arm will continue to deliver excellent wiping motion with minimal effort.
W50 Pantograph Arm Durability and Cost
Durability is one of the strongest selling points of the W50 pantograph arm for marine systems. Constructed from marine-grade stainless steel and electropolished to resist corrosion, it withstands years of exposure to saltwater spray, UV rays, and extreme temperatures. In real-world marine environments, it can easily outlast cheaper alternatives by 2–3 times, especially when paired with quality wiper blades.
As for cost, while premium-grade pantograph arms come with a higher upfront investment, their longer service life and reduced need for maintenance make them more economical in the long run. Replacement intervals are significantly extended, and the structural integrity remains intact even under heavy use.
Expert Advice and Pro Recommendations
Marine experts consistently recommend using the W50 pantograph arm for larger vessels or installations with panoramic windshields. The extended sweep range and even pressure distribution reduce the need for multiple wiper arms, simplifying maintenance and installation.
For best results, pair this arm with a high-quality wiper blade such as those made with silicone or dual-compound rubber. Also, when operating in salt-heavy environments, keep a backup arm onboard in case of mechanical damage during long trips.

- Cabin Cruisers: Mid-weight versions with flexible angle adjustment.
Selecting the right arm ensures performance, efficiency, and long-term satisfaction with your wiper system.
Detailed FAQ Section
How do I know if the W50 Pantograph Arm fits my wiper motor?
The W50 Pantograph Arm is compatible with most standard marine wiper motors that support pantograph systems. You’ll need to verify the motor shaft type (splined or tapered), the required sweep arc, and the secondary anchor point location. Manufacturers typically provide these specifications in the wiper system manual. If you’re upgrading from a pendulum arm, ensure your existing motor has pantograph compatibility. For exact fit, consult product dimensions and compatibility charts from All Boat Supplies.
What makes the W50 pantograph arm more durable than other marine wiper arms?
The W50 Pantograph Arm is constructed using electropolished stainless steel or heavy-duty corrosion-resistant metals, ensuring it withstands salt, moisture, UV, and vibration stress better than standard arms. Its dual-support architecture reduces mechanical fatigue and distributes blade pressure more evenly. Unlike single-pivot pendulum arms, pantograph arms resist torsional stress and maintain alignment longer. When maintained properly, the W50 can serve over 5+ years even under continuous marine use, making it a cost-effective, long-term investment.
Can I replace my current wiper arm with the W50 Pantograph Arm?
Yes, but with conditions. Your wiper motor must support pantograph operation and provide an anchor point for the secondary linkage. If your current system uses a pendulum arm, you may need to upgrade both the motor and mounting base. Check your current sweep pattern — pantograph arms operate in a dual-pivot arc, so clearance and sweep path will differ. It’s best to check the installation diagram and consult with marine hardware experts to ensure compatibility and fit.
How to maintain the W50 pantograph arm in a saltwater environment?
Saltwater environments are tough on all metal components. To maintain the W50 pantograph arm:
- Rinse with freshwater after each outing.
- Apply marine-grade anti-corrosion spray monthly.
- Lubricate moving joints and pivots with silicone lube.
- Inspect for cracks, rust spots, or stiffness in motion.
This routine ensures longevity and reliable performance throughout all seasons. Keep a log of your inspections to track wear-and-tear patterns.
What blades should I pair with the W50 pantograph arm?
The W50 pantograph arm is compatible with heavy-duty marine blades ranging from 24” to 30”, depending on windshield size and sweep arc. Opt for blades with dual-edge silicone or UV-resistant rubber for maximum wiping performance. Brands like Marinco, Exalto, and AFI offer compatible blades built for extreme marine environments. Ensure your blade’s connector matches the W50’s locking mechanism — usually J-hook, bayonet, or saddle type.
