Harken Black Magic Blocks

These high-performance blocks are found on boats of all sizes and are known for their superior load capacity compared to the Carbo Series.
This strength comes from their unique roller bearing system: a large cylinder with cage bearings to minimize friction and thrust bearings to handle misaligned loads.
Black Magic blocks come in various configurations, including swivel, soft shackle, double, and footblock options.
They are fully serviceable, meaning individual components can be replaced, ensuring long-lasting performance.
