• Why Slight Shaking? - Different cars have rear windows with varying curvatures, which is why we’ve specifically designed a slight shaking feature in the metal tube inside the suction device. This unique design allows the suction cup to automatically adjust to the angle of the glass, ensuring a perfect fit and achieving the best possible suction, even on windows with different radians.
• Safety Red Line Indicator - A built-in red line indicator on the suction cup acts as a safety installation guide. It constantly monitors the vacuum state and suction strength of the device. When the red line is visible, it indicates insufficient suction, and the device must be released and reattached to ensure a secure hold. Once the red line disappears, you know that the suction is at a safe and secure level, ready for use.
• Supports Up to 150 LBS - With two heavy-duty suction cups and aluminum bars, this kayak roller suction system can securely hold and support kayaks weighing up to 150 lbs. The combination of strong suction and robust materials ensures that the system can reliably carry your kayak from the ground to the top of your car without worry.
• 70° or 90° Angle Adjustable - With easy-to-install nuts, you can adjust the angle of the bracket to either 70° or 90°, making it compatible with a variety of rear window inclinations. This flexibility ensures the system works with most cars, SUVs, and jeeps, offering you the perfect fit for loading your kayak onto the car roof every time.
• Hourglass Roller Design - Featuring a 21.8-inch width U-shaped bracket, the hourglass-shaped rollers keep your kayak from sliding out during loading. The closer distance between the suction cups results in a smaller curvature difference, making it more stable and less likely to fall off during the loading process. This design ensures maximum stability while loading your kayak.
• V-Shape Rotating Foam - The V-shape rotating foam ensures that your kayak moves slowly and safely as it slides down. The 3.26-inch thick foam pad not only prevents scratches and damage to the hull but also provides extra protection during the loading process, ensuring your kayak remains safe and intact.
• Clean the Window Before Use - For optimal suction, always clean the rear windshield with a towel before installation. Afterward, press the two suction cups firmly to create a secure bond. Always double-check that the kayak roller is secure before using it to load your kayak onto the car top.
