Product Description Harken 13mm CB Battcar - Intermediate A Harken Battcar system along with full-length battens helps raise, douse, and reef with ease and acts as extra crew if you’re sailing shorthanded.

The free-rolling ball bearing cars let you hoist and reef the main quickly on all points of sail.
