Harken 1544 3" 76mm Double Midrange Classic Block
HARKEN 1544
Double Midrange Block - 76mm
Midrange blocks' robust construction makes them ideal to handle the high loads found on medium and large offshore boats. Sheaves run exclusively on ball bearing systems for fast trim and release under any load.
The free-rolling Delrin® ball bearings, sheave, and side plates are UV-stabilized with carbon-black additive for maximum protection. A stainless steel side strap wraps across the block head for increased strength and safety. (Delrin® is a registered trademark of E. I. du Pont de Nemours and Company or its affiliates.)
The wide-diameter 3.00" (76mm) ball bearing sheave accepts 9/16" (14mm) line. High-load Midrange blocks use Torlon® ball bearings. (Torlon® is a registered trademark of Solvay Advanced Polymers.)
