Harken 25mm Wire Thru Deck Block (HK302)
Wire blocks are lightweight, low-friction blocks designed to carry wire halyards and control lines on boats of all sizes.
To minimise friction from twisting or unfair leads, wire blocks feature sideload balls between the sheave and the sideplate.
High-load composite bearings carry axial loads. 25mm wire blocks use low-friction thrust washers.
Stainless Steel sideplates offer superb chafe resistance.
