HARKEN YACHT FITTINGS 80mm Aluminum Element Mastbase Block — Swivel
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 previously least expensive blocks.
The key difference between Element Blocks and other value ranges lies in the use of forged aluminium side plates, preventing distortion and wear and increasing the durability of the block. The sheaves are comprised of the same Nylon fibre as used in Harken's Carbo and Furling range. Side plates are hardcoat-anodized to resist corrosion. A tough composite bearing sheave resists corrosion for a long service life.
The range comes with a locking collar for the head post which can be removed to allow free spinning blocks or placed in one of two orientations at 90 degrees. For best performance, select a rope 1 size below the block's maximum line diameter.
