Product Overview
The Harken 57mm Black Magic Single Block includes an integral becket that allows either a 2:1 or 3:1 purchase. The entire line of Black Magic AirBlocks offer a sleek and polished look. Their unique performance engineering remains the staple of the Black Magic line of blocks. These strong, lightweight blocks feature free-rolling, high-load Torlon roller bearings for a high strength-to-weight ratio. Used for dynamic high load sail controls including mainsheets, runners, halyards and spinnaker systems. Air blocks are easy to clean and service. They have few parts and no loose balls or rollers to misplace. Unlike blocks that are riveted, fasteners allow quick disassembly with a single hex wrench.
