Description
Harken 80mm Aluminum Element Double Footblock
Element blocks introduce sideplates that combine forged aluminum 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. Sideplates are hardcoat-anodized to resist corrosion. Bearing sheave of tough composite resists corrosion for a long service life.
