Pantograph Arm Fixed Length – Durable, Easy Install, Best Price
Introduction
When visibility matters most, especially during harsh marine weather, choosing the right wiper arm is critical. The pantograph arm fixed length 31.5″ (800mm) is engineered to deliver uncompromising performance for marine professionals and recreational boaters alike. This robust wiper arm ensures maximum window coverage, consistent wiping action, and seamless integration with marine-grade wiper motors. Designed specifically for boats and marine engines, it is built with corrosion-resistant materials that withstand saltwater, UV rays, and vibration fatigue.
Whether you’re refitting your helm station or upgrading worn-out equipment, this arm provides the perfect blend of durability, precision, and performance. Its fixed length of 800mm ensures predictable wiping motion—ideal for pantograph systems where geometry and reach are crucial. Compatible with various wiper motor configurations, it works across an extensive range of boat models.
Overview / What Is a Pantograph Arm Fixed Length?
A pantograph arm fixed length refers to a specific design of wiper arm used in marine applications, especially where uniform and extended wiping coverage is essential. The pantograph mechanism operates with two connected arms that move in parallel, allowing the wiper blade to remain vertical throughout the wiping cycle. This movement covers more surface area and is ideal for large windshields typically found in pilot houses or commercial vessels.
The “fixed length” designation means that the arm is pre-sized—31.5 inches (800mm) in this case—and does not allow for manual adjustment. This makes it ideal for installations where consistency and geometry are critical. Marine-grade materials like stainless steel and anodized aluminum ensure that the arm resists rust, pitting, and UV degradation over time.
Advantages of Using Pantograph Arm Fixed Length on Marine Vessels
Marine conditions demand rugged and reliable equipment, and the pantograph arm fixed length delivers on both fronts. Here are some of the top benefits:
- Corrosion Resistance: Built from marine-grade materials, it resists corrosion and weathering.
- Enhanced Wiping Coverage: The pantograph design allows maximum windshield area to be cleared.
- Consistency: Fixed length eliminates error during installation—ensures proper blade motion.
- Compatibility: Works with several industry-standard marine wiper motors and blades.
This design is commonly seen on vessels such as fishing boats, patrol boats, sailboats, and offshore yachts. Pantograph systems are also preferred by OEMs and shipyards for their reliability and proven efficiency.
How to Install Pantograph Arm Fixed Length 31.5″ (800mm)
Installing a pantograph arm fixed length is straightforward with the right tools and instructions. Here’s a step-by-step guide:
- Safety First: Disconnect power to your wiper system before beginning installation.
- Remove Old Arm: If replacing, detach the previous arm using a suitable wrench or screwdriver.
- Align New Arm: Position the arm on the motor spindle ensuring the blade bracket aligns horizontally.
- Tighten Mount: Secure it using stainless screws or locking nuts provided with your wiper motor kit.
- Test Operation: Reconnect power and test the full sweep to confirm proper alignment and pressure.
It’s essential to ensure the wiper blade connected to this arm is marine-rated. We recommend pairing this arm with high-quality 22″–24″ marine wiper blades.
Maintenance Tips
To prolong the life of your pantograph arm fixed length, incorporate regular maintenance into your vessel care routine. These arms are durable, but marine exposure can wear any equipment over time.
- Rinse After Use: Always rinse with fresh water after exposure to salt spray to prevent corrosion buildup.
- Inspect Joints: Check the pantograph linkage points for looseness or corrosion every few months.
- Lubrication: Use a marine-grade lubricant on moving joints to reduce friction and wear.
- Replace Blades: Old or cracked wiper blades can strain the arm mechanism—replace as needed.
Keeping these components clean and properly aligned ensures smooth operation and avoids damage to the wiper motor and windshield.
How to Troubleshoot Pantograph Arm Fixed Length Issues
While the pantograph arm fixed length is designed for longevity, problems can occasionally arise. Common signs of trouble include skipping motion, uneven wiping, or strange noises during operation.
Here are possible causes and solutions:
- Loose Fasteners: Check and retighten any mounting bolts or connection screws.
- Corrosion: Clean rust-prone areas with a soft brush and apply anti-corrosive spray.
- Misalignment: Recalibrate the arm angle to ensure it aligns with the blade arc and windshield geometry.
- Motor Weakness: If the motor seems slow or stops mid-sweep, test the motor amperage and consider replacement.
Pantograph Arm Fixed Length Cost and Durability
Marine-grade pantograph arms are priced based on material quality, length, and compatibility. The pantograph arm fixed length 31.5″ falls within a premium yet reasonable range given its heavy-duty performance and corrosion resistance.
Expected life ranges from 3–5 years under average marine usage, but with proper care, it may last even longer. It’s a smart long-term investment compared to cheaper alternatives that corrode within a single season.

Expert Advice and Pro Recommendations
Experts in the marine industry consistently recommend pantograph arm fixed length setups for commercial-grade visibility. They are particularly effective in high-traffic ports and for vessels navigating at night or in inclement weather.
We suggest matching the wiper arm with a high-torque motor and heavy-duty blade system. Use only stainless steel or brass mounting hardware to prevent galvanic corrosion. Installation should be done with the vessel powered down to avoid electrical hazards.

Detailed FAQ Section
What is a pantograph arm fixed length and how does it differ from adjustable arms?
A pantograph arm fixed length is a specialized wiper arm used in marine vessels where precision and consistent sweep patterns are crucial. Unlike adjustable arms, which can be resized to fit varying applications, a fixed-length arm comes with a set dimension—31.5″ (800mm) in this case—ensuring no deviation in wiping geometry. The pantograph design allows dual-arm motion, keeping the blade vertical for uniform wiping. It’s ideal for larger windows and high-speed marine applications where stability and coverage are critical.
Is the 31.5″ pantograph arm compatible with all marine wiper motors?
This arm is compatible with most marine-grade wiper motors, especially Type 1.5 or ISO-standard spindles. However, always verify your motor’s spindle diameter and torque rating. The arm fits splined or tapered drive shafts commonly found in brands like Marinco, Exalto, and AFI. For optimal performance, pair with a motor capable of handling the mechanical load associated with a pantograph system. If unsure, consult a marine technician or reach out to our experts for fitment support.
How do I maintain a pantograph wiper system for long-term use?
Proper maintenance includes regular freshwater rinsing, visual inspections, and applying marine-grade lubricants to joints. Ensure the arm’s fasteners remain tight, and replace wiper blades every 12–18 months depending on use. Avoid forcefully lifting or adjusting the arm when the system is powered, as this may damage the mechanism. Store your vessel with wipers raised or shielded when out of service to prolong equipment life.
What are the signs that a pantograph arm needs replacement?
Common signs include visible corrosion, reduced wiping performance, skipping motion, and metal fatigue in joints. If the arm begins to wobble or fails to maintain a consistent wipe path, replacement is advised. Also, if the mounting section no longer grips the motor spindle securely, it may compromise safety and windshield clarity. Regular inspections help detect these early, preventing larger system failures at sea.
Can I install a pantograph arm fixed length myself?
Yes, installation is DIY-friendly for those with moderate mechanical skills. Ensure you have the correct tools—usually a hex wrench and marine-grade fasteners. The arm should align precisely with your blade and motor configuration. If replacing an old arm, use it as a reference. Always test the sweep path and adjust before securing fully. If unsure, contact a professional or use our expert chat feature for assistance and video guides.
