Harken 75mm Double Block

Harken 75mm Double Block

Product Details

    Technical 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. 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.
