Element blocks introduce sideplates that combine forged aluminum and compound curves for strength. They are simultaneously contemporary and very robust. The Element design pairs the minimum amount of metal required to protect the sheave with a proven journal bearing. Size for size, Element blocks are priced significantly lower than previous budget blocks from Harken. Sideplates are hardcoat-anodized to resist corrosion. A tough composite bearing sheave resists corrosion for a long service life.
