The AB Tools Rubber Keel Flat Roller and Bracket is designed for boat owners, jetski enthusiasts, and dinghy operators who require a durable, impact-absorbing support system for their trailer. This high-quality, OEM-standard replacement provides superior hull protection compared to traditional plastic rollers; however, users should verify their trailer's mounting hole spacing, as the M10 elongated slots accommodate a specific range of 50mm to 80mm hole centers.

This roller is designed for small craft such as jetskis and dinghies. Check your boat's total weight against the load-bearing capacity recommended by your trailer manufacturer.
The internal bore size of the roller is 16mm.
The unit includes the roller, bracket, and 16mm spindle. You will need to provide your own M10 bolts to secure the bracket to your trailer.
The steel bracket is plated to prevent corrosion, making it suitable for marine use, though regular fresh-water rinsing is recommended.
The bracket measures 148mm in total width.
Check for debris trapped between the roller and spindle, or apply a small amount of marine-grade lubricant.
Verify that your trailer mounting centers are between 50mm and 80mm; if they fall outside this range, you may need a different bracket style.
Ensure the spindle is correctly seated and that there are no missing washers or spacers included in your specific trailer setup.
To install, align the M10 elongated mounting holes of the bracket with your trailer's existing cross-member mounting points. Ensure the center-to-center distance falls between 50mm and 80mm. Secure the bracket firmly using appropriate M10 hardware. Periodic maintenance is recommended: rinse the roller and bracket with fresh water after saltwater exposure to prevent long-term corrosion. Inspect the rubber surface for wear or debris that could impede rotation. If the roller becomes stiff, apply a light, marine-grade lubricant to the 16mm spindle.
