HARKEN Element Blocks - Aluminum Sideplates & Composite Sheave

HARKEN Element blocks are engineered for sailing rigging hardware, offering a balance of strength, corrosion resistance and value. Element sideplates combine forged aluminum and compound curves for strength while remaining lightweight; sideplates are hardcoat-anodized to resist corrosion. The sheave is a tough composite bearing that resists corrosion for long service life, paired with a proven journal bearing. Element’s design uses the minimum amount of metal required to protect the sheave, delivering robust performance across sheeting, halyard and control applications. The Element line provides reliable, corrosion-resistant blocks for a variety of sailing rigging needs.
