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 sheave for strength and corrosion resistance.
25 mm (1.00") wire blocks use low-friction thrust washers. 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.
