Harken 60mm Element Triple Blocks. They are simultaneously contemporary and very robust. Element's design pairs the minimum amount of metal required to protect the sheave with a proven journal bearing. So size for size Element is priced significantly lower than their previously least expensive blocks. Sideplates are hard-coat-anodized to resist corrosion. A tough composite bearing sheave resists corrosion for long service life. Package Contents: Harken 60mm Element Triple Block Harken 6275: 60mm Element Triple Blocks
