Harken wooden blocks combine the warm appeal of old-world craftsmanship with durable, low-friction, high-strength Harken ULC bearing systems. Block shells are crafted from hand-selected, classic maritime elm which resists splitting and does not dry out. A gloss finish protects the wood from the elements and gives it a deep, rich shine.
