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.
