HARKEN 57MM ALUMINUM LOW LOAD BLACK MAGIC BLOCK W/SWIVEL

Harken 57mm Aluminum Low Load Black Magic Block w/Swivel

57mm Aluminum Low Load Black Magic Block with Swivel

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. Shackle blocks lock in two directions or swivel to keep the line from twisting. Low-load blocks have red isolators. They use Torlon® rollers and 316 stainless steel shackles. Standard blocks have 17-4 PH stainless head posts. Torlon is a registered trademark of Solvay Advanced Polymers L.L.C.
