  • McKissick Roll-Forged™ sheaves are available in sizes from 305mm to 1981mm. They are engineered to provide maximum hardness for wear-resistance and a closer fit for wire rope. With McKissick Roll-Forged Sheaves you can expect better balance and distribution of forces instead of uneven stress and failure that other sheaves face.
