Product Overview

Harken 75mm Double Footblock allows clean deck organization and 180° line angles. 

The entire line of Black Magic® AirBlocks® offer unique performance engineering which remains the staple of the Black Magic® line of blocks. These strong, lightweight blocks feature free-rolling, high-load Torlon® roller bearings for a high strength-to-weight ratio. Used for dynamic high-load sail controls including mainsheets, runners, halyards and spinnaker systems. Harken created the Black Magic® line of blocks for the high performance sailor in mind.

Air blocks are easy to clean and service. They have few parts and no loose balls or rollers to misplace. Unlike blocks that are riveted, fasteners allow quick disassembly with a single hex wrench.
