Harken 57mm ESP Footblock
Harken's ESP line (Elegant Simple Products) complements other Harken blocks in look and function but the blocks are simpler in design and construction.
Cruising ESP blocks complement our existing blocks in looks and function. Sheaves feature sleeve bearings to handle high static loads and are ideal for halyards or limited purchase systems on cruising boats.
