Harken 57mm High Load Block – Black Magic Air (3215)


Elite performance for high-load, high-action sail control systems

The Harken 57mm High Load Block (3215) from the Black Magic® Air series is engineered for the demands of big boat racers and performance cruisers, delivering smooth operation and exceptional load-handling capacity. Ideal for heavily-used systems such as mainsheets, runners, halyards, and spinnaker controls, this block offers top-tier efficiency and durability where it matters most.

Its lightweight aluminium sideplates house a high-load bearing system featuring Torlon® roller bearings and a central cage that keeps the rollers aligned and separated, significantly reducing friction under extreme loads. The result is a block that runs freely and consistently, even under constant tension and repeated trimming.

The versatile shackle head can be locked in two positions or allowed to swivel, helping to prevent line twist while adapting to a range of rigging angles and lead directions. Whether used on deck or aloft, the 3215 is a trusted choice for pro sailors and offshore programs that demand reliable, high-load performance.
