100 mm Aluminum ESP Footblock

ESP stands for Elegant Simple Products, which is a line of hardware that complements other existing Harken blocks in looks, but is simpler in design and construction. Sheaves feature sleeve bearings to handle high static loads and are ideal for halyards or limited purchase systems on cruising boats.
