These teardrop mast collar blocks coordinate well with any Harken blocks in a deck layout. Sheaves feature sleeve bearings to handle high static loads and are ideal for halyards or limited purchase systems on cruising boats. Use the blocks for direct attachment to padeyes, mast collar posts, perforated mast collars, or in mastbase situations where leads might change.
ESP stands for Elegant Simple Products, which is a line of hardware that complements other existing blocks in looks but is simpler in design and construction.
