Product Description

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. Available in aluminum or hand-polished stainless steel.

Use footblocks to redirect lines on the deck. Footblocks with lockoffs temporarily secure sheets and are designed for port or starboard installation by flipping them over.
