Harken 75mm Aluminum Loop Block

$455.99
Item Number: 3230

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.

The sheave center carries primary load, allowing a smaller, lighter weight block. The soft-attachment Loop block has a removable deadend post for attachment to a padeye. Lashings can also be used.
