Boat Trailer 6″ Grey Sydney Type Rubber Keel Roller – 15mm Bore, Non Marking (SKU: CRGR158X16)

The CRGR158X16 is a classic 6-inch Sydney type keel roller made from non-marking grey rubber. Designed for smaller boats with delicate hulls, it’s perfect for fibreglass boats needing extra care during loading and unloading.

The 15mm bore provides a tight, press-fit onto standard 16mm shafts, and the roller stays fixed while the shaft rotates inside the trailer bracket. With 75 DURO hardness, this unit gives the perfect balance between shock absorption and durability.
