Harken Wire & High Strength Blocks


Harken Wire & High Strength Blocks

Lightweight, low-friction wire blocks carry wire halyards and high-strength control lines on boats of all sizes. High-load composite bearings carry axial loads. Hardkote-anodized Teflon® impregnated sheave for strength and corrosion resistance. 25 mm (1.00 in) wire blocks use low-friction thrust washers. 38 mm (1.50 in) and 51 mm (2.00 in) wire blocks feature sideload balls between the sheave and the sideplate to minimize friction from unfair leads. 466 Features a forkhead and becket making it useful for vangs, halyards and control lines. Use for:
  • Wire halyards
  • Vangs
  • Control lines
