Harken 2646 Carbo 40 mm Sailing Block

The low friction Carbo Air blocks are light, strong, reliable and affordable. Together with the popular Harken Black Magic block, these small, compact blocks have a very high workload for safe and light trimming. Multiple rolls (violin rollers) can be built with simple three- and four-stroke hoists. Conserving large and small discs prevents friction ropes and ensures easy running.
