Harken's Element Single Footblock has hardcoat-anodized sideplates that resist corrosion. The sideplates combine forged aluminum and compound curves for strength. Element Single Footblock is simultaneously contemporary and very robust. The design pairs the minimum amount of metal required to protect the sheave with a proven journal bearing. A tough composite bearing sheave resists corrosion for a long service life.
