Harken 57mm ESP Footblock allows redirection of lines on the deck.
Designed to handle the high loads generated by modern racing and cruising boats, ESP blocks feature sleeve bearings to ensure smooth, hitch-free performance under high loads and heavy winds. Simple design and construction for handling high static loads on cruising boats. Ideal for halyards or limited purchase systems on cruising boats. Aluminum or polished stainless steel.
If double stacked, the upper block/organizer is two-thirds of the listed MWL and breaking load.
