    3" Midrange Double Block

    Harken 3" Midrange Double Block


    Product description

    Midrange Classic

    Midrange blocks’ robust construction makes them ideal to handle the high loads found on medium and large offshore boats. 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.

    The wide-diameter 3.00 in (76 mm) ball bearing sheave accepts 9/16 in (14 mm) line. High-load Midrange blocks use Torlon® ball bearings.

    Delrin® is a registered trademark of E. I. du Pont de Nemours and Company or its affiliates. Torlon® is a registered trademark of Solvay Advanced Polymers.
