Harken Black Magic Air Blocks 45 mm Aluminum Block, Swivel
Reference HK3391Harken Black Magic Air Blocks 45 mm Aluminum Block, Swivel
Black Magic air blocks are a top favorite of Big Boat performance racers and cruisers. These lightweight, free-running, powerful performers are used for sail controls that see lots of action: mainsheet, runner, halyard, and spinnaker systems. A center cage keeps Torlon® roller bearings separated and parallel to reduce friction. Shackle blocks lock in two directions or swivel to keep line from twisting. Torlon is a registered trademark of Solvay Advanced Polymers L.L.C.
