Black Magic Air blocks are a top favourite 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.

The soft-attachment Loop Block has a removable deadend post for attachment to a padeye. Lashings can also be used
