Cruising ESP Blocks - 57 & 75mm
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.
