Product information "Harken ESP Swivel Block 57mm"
Harken introduced the ESP block range specifically with the cruising sailor in mind. Whilst the blocks are slightly simpler in design than some of their racing siblings, there is no doubting the quality and engineering of this aluminium swivel block. Perfect for halyards or systems with limited purchase, the ESP block has sleeve bearings to handle high static loads. The teardrop design and swivel make attachment easy whilst keeping things nice and tidy on deck.
