Tie Down Engineering 86479 4" Spool Keel Roller 1/2" Shaft Bore Black Rubber

The Tie Down Engineering 86479 is a 4-inch black rubber spool-type keel roller designed for boat trailers. Built to center and guide your boat's keel during loading and unloading, this roller helps keep your boat properly aligned on the trailer, preventing side-to-side shifting and simplifying both launching and retrieval.

Constructed from durable rubber, this keel roller is built to resist abrasion and salt corrosion, making it suitable for use in both freshwater and saltwater environments. The spool-style profile fits a 1/2-inch shaft and provides a smooth rolling surface that protects your hull during trailer use.

Key Features:

• 4-inch spool-type rubber keel roller
• Fits 1/2-inch shaft (1/2-inch center hole)
• Black rubber construction for durability and hull protection
• Resists abrasion and salt corrosion for long-lasting marine use
• Helps center and align boat keel during loading and unloading
• Can be used in multiples along the trailer for improved load distribution
• Serves as a direct replacement for warped or distorted keel rollers

The Tie Down Engineering 86479 is an ideal replacement roller for worn or damaged boat trailer keel rollers. Using multiple rollers along the trailer's cross members helps distribute the boat's weight more evenly, reducing contact stress and protecting the hull and trailer structure alike.
