Tie Down's Keel Roller is a versatile and essential component for your boat trailer. Tie Down's Keel Roller serves as a replacement part for any warped or distorted rollers. The primary function of the keel roller is to center and guide the keel of your boat onto the trailer during loading and unloading. By providing a smooth and controlled surface, it helps prevent the boat from shifting side to side and ensures proper alignment, simplifying the launching and retrieval process. Using multiple keel rollers at once offers even greater benefits. With several rollers strategically positioned along the trailer's cross members or axles, you can distribute the load and support the boat more effectively. This helps prevent the boat from cross members or axle contact, minimizing potential damage and wear. Constructed with durability in mind, the keel roller is designed to withstand abrasion and resist salt corrosion, making it suitable for both freshwater and saltwater environments. This ensures long-lasting performance and reliable functionality, even in harsh marine conditions.
