Harken 100mm Double Swivel Block
100 mm Black Magic AirBlocks are used on offshore boats where weight and performance are critical. These strong, lightweight blocks are used for sheets, halyard, running backstay, and control line assemblies on offshore boats.
They feature strong and long-lasting Torlon roller bearings housed in a center cage with sculpted hardcoat-anodized aluminum sideplates to protect the sideload ball bearings.
Corrosion is minimized by isolating dissimilar metals. They can be taken apart with a single hex wrench. The 3245soft-attachment Loop Block has a removable dead-end post for attachment to a pad eye. Lashings can also be used. The loop is not included.
