    Harken Black Magic 75mm Double Block wirh Swivel


    Product description

    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.

    The entire line of Black Magic Air blocks has been redesigned with a sleek new look. Their unique, performance-packed engineering remains exactly the same. These strong, lightweight blocks feature free-rolling high-load Torlon® roller bearings for a high strength-to weight ratio.

    Sideplates and sheaves Hard Lube-anodized for maximum UV protection and a smooth surface.

    Center cage keeps Torlon® roller bearings separated and parallel to reduce friction.
