Harken Blocks - Stainless Steel Blocks
Harken's line of stainless steel blocks reflect the traditional beauty of your yacht's classic lines. Stainless sideplates are mirror-polished for durability and unmatched esthetics. The ultralight composite bearing system (ULC) rides on a heat-treated stainless steel inner race to handle extremely high loads. Snap-fit Torlon® ball bearings carry thrust loads.
