100 mm Roller Bearing Blocks (RBB 100)

A 100 mm sheave carrying 3,500 kg on lines up to 16 mm. At this size the question is no longer which way the line leaves the block, there are no cheek or flip-flop versions up here, but how the block attaches to the boat. The three RBB 100 versions answer that three different ways: a stainless shackle, a stand-up base, or a soft lashing.
