Description
Description
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.
Low-load blocks have red isolators. They use Torlon rollers and 316 stainless steel shackles. Standard blocks have 17-4 PH stainless headposts.
Torlon is a registered trademark of Solvay Advanced Polymers L.L.C.
