Harken Block - Black Magic 100mm Single - Swivel / Becket

$780.95 USD $976.19

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.

Torlon is a registered trademark of Solvay Advanced Polymers L.L.C.
