HARKEN ESP FOOTBLOCK 100MM
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.

If double stacked, upper block/organizer is two-thirds of listed MWL and?breaking load.
