Single Cruising ESP Collar Block - 57

Aluminum

ESP stands for Elegant Simple Products. Cruising ESP blocks have a simpler construction and bearing system than Black Magic® or Harken stainless steel blocks, but they complement these lines with similar aesthetics. These ESPs are strong, reliable, and cost-effective. Sheaves feature sleeve bearings to handle high static loads and are ideal for halyards or limited purchase systems on cruising boats.


Teardrop Blocks
Use Cruising ESP teardrop blocks for direct attachment to padeyes, mast collar posts, perforated mast collars, or in mast-base situations where leads might change.
