57 mm Black Magic Air Aluminium Triple Block — Swivel

$1,070.05 incl GST

Description

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. A centre 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.
