Product Details

The Tie Down Engineering 86485 is a 10-inch molded rubber center guide keel roller designed to protect your boat and simplify trailer loading and retrieval. Built for use on standard boat trailers, this roller fits shafts with a 5/8-inch diameter and is an ideal replacement for worn, warped, or distorted rollers.

Key Features:

  • Center-Guide Design: Centers and guides the keel of your boat onto the trailer for precise alignment during loading and unloading
  • Molded Rubber Construction: Black rubber material with nylon inserts for smooth, free-spinning performance that reduces drag while launching
  • Cut & Abrasion Resistant: Durable rubber compound resists cutting and abrasion, extending service life under repeated use
  • Salt & Freshwater Compatible: Engineered to resist salt corrosion, making it suitable for both freshwater and saltwater environments
  • Specifications: 10-inch roller length, 3-inch outer diameter, 5/8-inch shaft bore, black finish
  • Prevents Hull Damage: Keeps the boat from contacting cross members or trailer axles, minimizing wear and potential damage to the hull

Using multiple keel rollers positioned along the trailer's cross members allows for better load distribution and improved hull support during transport. The Tie Down Engineering 86485 is a reliable, drop-in replacement that restores proper trailer function quickly and easily.

Delivery man was excellent. The AC unit was plug and play.

I never received anything about shipping so I contacted customer support. They said it was a direct shipment and they would check on it for me and get back to me. I never heard back from them. Shortly after that I did receive a message from the carrier saying they have my shipment and scheduled a delivery. They said they would call me 30 mins before the delivery so I could get off work and come to inspect it before signing for it. That didnt' happen either my wife called me first thing in the morning and say they are here delivering it now so I had to run home so I could inspect it. The driver was really nice and waited for me to get there.

Wasn't happy with the extra charges for handling. Do not see that until I paid it.

Good price and fast delivery.
