51 mm 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. Hard Lube-anodized sheave for strength and corrosion resistance. 51 mm (2") wire blocks feature sideload balls between the sheave and the sideplate to minimize friction from unfair leads. They offer superb chafe resistance with wire halyards and controls.

• Hard Lube-anodized
• Sideload balls between the sheave and the sideplate to minimize friction
