Molded from an enhanced polyvinyl chloride (PVC) formula, this amber roller is non-marring so it will not mark or mar the hull, while remaining cut resistant and able to absorb shock during loading. Tie Down Engineering notes that its enhanced PVC formula outperforms traditional polyurethane rollers in durability and long-term wear.\u003c\/p\u003e\u003cp\u003eThis roller measures 8 inches in length and is sized for a 5\/8 inch shaft, making it a direct fit for trailers built around that shaft diameter. It mounts along the keel section of the trailer frame to guide and stabilize the boat during loading, helping maintain proper hull alignment and protecting the hull surface across the trailer's cross members. The roller is also offered by Tie Down Engineering in 10 inch and 12 inch amber lengths, as well as 8, 10, and 12 inch black versions, each under its own separate part number, so boat owners can match roller length and color to their specific trailer setup.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Tie Down Engineering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 86159\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Amber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polyvinyl Chloride (PVC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Size:\u003c\/strong\u003e 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoller Length:\u003c\/strong\u003e 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoller Width:\u003c\/strong\u003e 0.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e Water resistant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Use:\u003c\/strong\u003e Boat trailer keel support\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits boat trailers using a 5\/8 inch keel roller shaft.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat shaft size does the Tie Down Engineering 86159 keel roller fit?\u003c\/strong\u003e The 86159 keel roller is sized for a 5\/8 inch shaft, so it is intended for boat trailers built around that shaft diameter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color and length is part number 86159?\u003c\/strong\u003e Part number 86159 is the amber colored keel roller measuring 8 inches in length.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this roller made of PVC or polyurethane?\u003c\/strong\u003e This roller is molded from an enhanced polyvinyl chloride (PVC) formula, which Tie Down Engineering states outperforms traditional polyurethane rollers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this roller mark or scratch the hull of my boat?\u003c\/strong\u003e No. The 86159 PVC keel roller is non-marring and will not mark or mar the boat's hull.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 86159 keel roller weigh?\u003c\/strong\u003e The Tie Down Engineering 86159 keel roller weighs 2.12 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes Tie Down Engineering make this roller in other lengths or colors?\u003c\/strong\u003e Yes.
