Harkens Midrange Blocks have a robust construction that makes them ideal for handling the high loads often found on medium and large offshore boats.
Sheave runs exclusively on a ball bearing system for fast trim and release under any load. The wide-diameter 76 mm (3.00 in) ball bearing sheave accepts 14 mm (9/16 in) line.
Delrin® ball bearings, sheave, and sideplates are all UV-stabilized with carbon black for maximum protection. A stainless steel sidestrap wraps across the block head for increased strength and safety.
