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. Hard Lube-anodized with PTFE impregnation 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.
