Black Magic Air Blocks

Runners are designed for use on the running backstays of offshore boats, allowing for precise adjustment of mast bend to accommodate varying wind conditions. The construction features integrated sideplate bails and recessed cotter keys, creating a smooth profile that prevents snagging on lifelines. Hard Lube-anodized sideplates and sheaves provide maximum UV protection and a smooth surface fini... read+

Teardrop blocks are ideal as masthead leads and in other applications where limited articulation or direct attachment is desired. When attached to a compatible padeye, these blocks will not hit the deck when lines are slack, but allow enough movement to ensure fairleads when jumping halyards. They are often used on permanent backstays of fractionally rigged boats where the backstay can be splic... read+

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 tw... read+
