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 line from twisting. Torlon is a registered trademark of Solvay Advanced Polymers L.L.C.
The Black Magic Double Pulley has a central Torlon Roller Bearing. Easy maintenance with one hex screw for disassembly. All bearings remain captive. The swivel post can fully rotate or be locked in two directions
