This lightweight, low-friction Harken Wire Block is designed to carry wire halyards and high-strength control lines where the line is not adjusted frequently. Perfect for backstay systems along or coupled with corresponding split backstay plates on boats of all sizes.
High-load, composite bearings carry axial loads. The sheave is Hardkote-anodized and Teflon impregnated for strength and corrosion resistance.
This model comes with a standard non-reinforced coverplate. Reinforced coverplates are sold separately and do not include the block assembly.
