Harken 57mm Black Magic Blocks

Harken 57mm Black Magic 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.

Black Magic blocks have a modular parts system allowing majority of the parts to be serviced and replaced. Side plates, ball bearings, head posts etc are all replaceable. Just remove the 3 allen bolts and the side plate to service. We have seen these blocks in great condition on 15 year old boats!
