Harken Midrange Blocks

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

Free-rolling Delrin® ball bearings, sheave and sideplates UV-stabilized with carbon-black additive 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.
