$592.95$1,794.95 incl GST

Description

Harken 57mm-100mm Black Magic Air Single Becket Block are a top favourite of Big Boat performance racers and cruisers. Also, 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. In addition, 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.
