Key Features and Benefits
Superior Weather Performance - Graphite-Treated Edge
Graphite-treated natural rubber edge removes even the smallest water droplets while the all-steel frame resists corrosion and maintains contact pressure at highway speeds. Delivers crystal-clear visibility in rain, snow, and road spray conditions.
Fleet-Ready Installation - DirectConnect System
DirectConnect system installs in seconds without adapters on 90% of vehicles. Fits popular wiper arm types including 9x3mm Hook, 9x4mm Hook, and both small and large pin connections for universal compatibility across fleet vehicles.
Proven Durability - All-Steel Construction
Dual steel tension springs and aerodynamic vented frame design prevent blade lift-off and reduce noise. Built to withstand extreme weather and high-mileage use that commercial and fleet applications demand for reliable service.
| Feature | Benefit |
|---|---|
| DirectConnect Installation System | Revolutionary quick-clip technology eliminates adapters and tools completely, working seamlessly with hook, pin, and bayonet arms found on 90% of commercial and passenger vehicles. Installation takes less than 30 seconds per blade with intuitive alignment guides and audible click confirmation. The foolproof connection design prevents improper installation while ensuring secure attachment that won't come loose during operation, even in extreme weather conditions or demanding commercial driving scenarios. |
| Dual Steel Tension Springs | Advanced spring-loaded pressure distribution system maintains optimal blade-to-glass contact across the entire 28-inch windshield surface, automatically adapting to curved glass profiles found on modern commercial vehicles and trucks. This ensures complete water removal without gaps, streaking, or missed spots that compromise driver visibility. The dual spring design also prevents excessive pressure that can cause premature wear while maintaining consistent performance throughout the blade's extended service life. |
| Graphite-Treated Rubber Edge | Precision-cut natural rubber with advanced graphite coating provides ultra-smooth operation and eliminates annoying blade chatter completely across all windshield surfaces. The specially formulated compound resists heat, ozone, salt corrosion, and UV deterioration while maintaining optimal flexibility in extreme temperatures from -40°F to 140°F. This enhanced rubber formulation delivers consistent wiping performance throughout the entire service life, ensuring crystal-clear visibility in demanding commercial applications including heavy rain, snow, and road debris. |
| Aerodynamic Steel Frame with Zinc Coating | Heavy-duty all-steel frame with flow-through aerodynamic design prevents dangerous wind lift at highway speeds while maintaining optimal blade-to-glass contact pressure across curved windshields. The zinc dichromate coating provides superior corrosion resistance against road salt, moisture, and chemical exposure common in commercial operations. This professional-grade construction ensures reliable operation in demanding fleet applications where vehicle downtime is not acceptable and consistent performance is critical for safety. |
| Professional Bulk Pack Value | Ten-pack quantity provides significant cost savings for automotive shops, fleet managers, and commercial operators who need reliable inventory on hand for immediate service needs. Having multiple 28-inch blades in stock reduces vehicle downtime and ensures you're always ready for the next installation without reordering frequently. The bulk packaging reduces per-unit costs while maintaining the same premium quality and performance standards as individual retail packages, making it perfect for high-volume professional applications. |
