Harken ESP (Elegant Simple Products) blocks complement other Harken blocks in looks and function, and are simpler in design and construction, making them ideal for halyard or limited purchase systems on cruising boats or for production boats with mounting posts on the mast collar. Sheaves feature axle bearings to handle high static loads.

Mast collar blocks vary depending on application. Use the Pad eye teardrop blocks to mount to pad eyes, and the teardrop-shaped Mast blocks for direct attachment to pad eyes or mast collar posts to keep lines extremely close to the deck.
