Harken Cruising ESP Blocks 57mm - 100mm
Cruising ESP blocks are strong, reliable and cost-effective. Similar to other Harken blocks in looks and function, but simpler in design and construction. Sheaves feature a high-strength axle bearing with sleeve bearings to handle high static loads and are ideal for halyards, running backstays, mastbase leads, and other applications with high static loads (loads that do not need constant adjustment).
Available in aluminum or hand-polished stainless steel.
Use teardrop blocks for direct attachment to padeyes, mast collar posts and mastbase installations.
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.
Swivels and Fiddles
Use cruising ESP swivel and fiddle blocks in winchdriven purchases of 4:1 or less. Perfect for running backstays, vangs or mainsheet systems on cruising boats from 35 ft to 45 ft (10 m to 14 m).
