SELDÉN ROLLER
BEARING BLOCKS

 

Low resistance at high, dynamic loads is the main characteristic of Seldén Roller Bearing Blocks (RBB). The ability to easily release a highly loaded backstay tackle, a main sheet, a spinnaker halyard or a kicker tackle makes for fast, safe and uncomplicated manoeuvers.

 

You will find yourself focusing on what really matters - boat speed.
