When Harken sets out to create a block for sailors who have always believed they didn’t need Harken, what happens? The new Element block. The name hints at its essence: everything that doesn’t contribute durability or strength is stripped away. The result is an economical block that does a Harken job. Element blocks accept line from 8 - 16 mm. They are offered in singles, doubles, triples, fiddles, and footblocks in 45, 60 and 80 mm sizes.
