A ball bearing single swivel sailing block that provides excellent sheave rotation with the lowest possible friction. Stainless steel ball bearings and a glass fibre reinforced sheave provide superior strength, even under high dynamic loads. An acetal bearing cage prevents ball-to-ball friction and keeps weight down.
