Hard blue nylon boat trailer rollers, the tough, low-friction choice for aluminium (tinnie) and heavier alloy hulls that launch often. Blue nylon rollers carry heavy loads and shrug off wear where softer rollers would mark or flatten. Viking Rollers stocks the blue nylon range: keel, bow, Sydney, concave, self-centring and rope rollers, plus front end caps, for the trade Australia-wide.
