Description
Harken 60mm-80mm Element Mast-Base Block introduce side-plates that combine forged aluminium and compound curves for strength. 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 our previously least expensive blocks.
Side-plates are hard-coat anodised to resist corrosion. A tough composite bearing sheave resists corrosion for a long service life.
