Sale price$121.95 Regular price$138.05

HARKEN 310 

Single Line/Wire High Strength Thru-Deck Block

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 PTFE-impregnated sheaves provide strength and corrosion resistance.

51mm (2.00") wire blocks feature side-load balls between the sheave and the side plate to minimize friction from unfair leads.

Use for:
  • Wire halyards
  • Vangs
  • Control lines
