Harken 57mm Low Load Block w/Becket
$263.95
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. 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.
