Harken 2621 Fiddle Purjeveneen ploki

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.
