Harken Midrange Classic Blocks have a robust construction that makes them ideal to handle the high loads found on medium and large offshore boats. The sheave runs exclusively on a ball bearing system for fast trim and release under any load.
Delrin® ball bearings, sheave, and sideplates are UV stabilized with carbon black for maximum protection. A stainless steel sidestrap wraps across the block head for increased strength and safety.
