Harken 57mm Black Magic Block with Swivel
This lightweight and highly efficient 57mm Black Magic Block is specifically designed for big boat performance races and cruisers. Renowned for their free-running capabilities, these blocks excel in demanding sail controls including mainsheets, runners, halyards, and spinnakers. The innovative center cage design keeps Torlon® roller bearings in perfect alignment, minimizing friction during high-load scenarios. These shackle blocks can be secured in two directions or swivel to prevent line twisting, enhancing user convenience. Low-load variants come with red isolators and utilize durable Torlon® rollers combined with robust 316 stainless steel shackles for longevity. Standard blocks incorporate 17-4 PH stainless head posts for added strength.
