HARKEN BLOCK ESP MAST COLLAR 40MM

Cruising ESP blocks complement our existing blocks in looks and function, but are 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.

Use teardrop blocks for direct attachment to padeyes, mast collar posts, perforated mast collars, or in mastbase situations where leads might change.
