attwood keel roller spool and bracket assembly One Size — 3" molded-rubber roller, zinc-plated bracket

If you move your boat on and off a trailer, the right roller assembly reduces impact, prevents hull scuffs, and guides the keel for smoother launches and hauls. This Attwood kit includes the proven 11210 molded-rubber roller combined with the 11252 zinc-plated steel bracket so you get a ready-to-fit spool and keel assembly that mounts to standard cross-roller fixture points.

How does this assembly protect my boat when loading onto a trailer?

The molded rubber roller absorbs shock and distributes contact over a larger surface than bare metal, minimizing pressure points on the keel. The spool/bracket design keeps the roller centered so the boat rides evenly as it rolls on or off the trailer.

• 3-inch diameter by 4-inch long molded rubber keel minimizes hull wear
• 5/8-inch nylon inserts provide smooth axle rotation and reduced friction
• Zinc-plated formed steel bracket resists corrosion and holds alignment
• 1/2-inch adjustment slot allows precise positioning for various hull shapes

What makes the Attwood 11220-3 easy to install and adjust?

The assembly is built to mount to common trailer cross-roller points, so installation often uses the same holes or bracket connections as existing rollers. The bracket’s 1/2-inch-wide slot gives simple fore-and-aft adjustment without custom fabrication, and the spool/roller arrives complete so you won’t need extra parts to make it operational.

• Complete spool and bracket included—no separate ordering of roller or bracket
• Half-inch slot for quick alignment and bolt repositioning
• Standard nylon insert sizes fit common trailer fasteners and axles
• Zinc-plated bracket fits marine environments with improved corrosion resistance

Which materials and dimensions should I expect from this roller assembly?

Attwood paired a tough molded rubber roller with nylon inserts and a formed steel bracket to balance resilience, low friction, and structural strength. The roller is sized to cradle keels without concentrating loads, and the bracket profile gives both mounting rigidity and adjustment range for different trailers and hull profiles.

• Roller: molded rubber, 3 inches diameter by 4 inches long
• Inserts: 5/8-inch diameter nylon for smooth rotation
• Bracket: formed steel, zinc-plated for corrosion resistance
• Adjustment: 1/2-inch-wide slot for bolt positioning and tuning

Who is this for? The Attwood 11220-3 is intended for boat owners, trailer shops, and marine technicians who want a reliable, easy-to-fit keel roller that reduces hull wear and improves trailer guidance. It’s especially useful for trailered runabouts, fishing boats, and small cruisers where consistent hull support and straightforward installation matter most. If you need a replacement or upgrade that pairs proven rubber cushioning with a corrosion-resistant bracket and convenient adjustment, this complete assembly is a practical choice.
