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
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.
