Harken Midrange Single Blocks

Harken Midrange Single Blocks are used for main sheets, spinnaker sheets, halyards and control lines. 3 Inch diameter sheave with robust construction is ideal for high loads 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 inch (76 mm) ball bearing sheave accepts 9/16 in (14 mm) line. High-load Midrange blocks use Torlon ball bearings.
