Harken's 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 and a hard Lube-anodized sheave for strength and corrosion resistance. 

The Harken 38 mm (1.50") and 51 mm (2.00") wire blocks feature sideload balls between the sheave and the sideplate to minimize friction from unfair leads.
