Harken 57 mm Aluminum Loop Block

Product Description Harken 75mm Aluminum Loop BlockDescription - The entire line of Black Magic AirBlocks 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. The 3230 soft attachment Loop block has a removable dead-end post for attachment to a padeye. #desdes# 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. The sheave center carries primary load, allowing a smaller, lighter weight block.
