4.5″ Boat Trailer Keel Centre Roller – Black Rubber, 115mm x 17mm Bore

This black rubber keel centre roller is built to provide reliable support and smooth guidance for your boat during launching and retrieval. Measuring 115mm in width with a 17mm bore, it is suitable for use with a 16mm spindle and is ideal for fiberglass boats that require extra care when loading.

Key Features:

• 4.5-inch (115mm) keel roller made of heavy-duty black rubber
• 17mm bore diameter – designed for 16mm spindle use
• Cotton reel profile for stable and centred keel alignment
• Durable and UV-stable – resists wear from sunlight exposure
• Gentle on fiberglass hulls – prevents scratches and marks

Why Choose This Roller?

Fiberglass boats demand rollers that protect the hull from pressure points and abrasion. This rubber keel centre roller offers the right balance of firmness and flexibility, making it safer than hard plastic alternatives. Its cotton reel shape naturally helps keep the boat aligned, reducing the chance of misloading and trailer damage.

Installation & Use

Installation is quick – simply slide the roller onto a 16mm spindle and secure it. Check periodically for wear, and replace when necessary to keep your trailer working smoothly. A little lubrication on the spindle will keep the roller turning freely and extend its service life.

Whether you are upgrading your trailer or replacing worn parts, this 4.5-inch centre roller is a practical and affordable solution for keeping your boat safe during loading and transport.
