Harken 57mm Loop Block
$253.95
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. The sheave center
carries primary load, allowing a smaller, lighter weight block.The
soft-attachment Loop block has a removable deadend post for attachment
to a padeye. Lashings can also be used.
