Selden RBB range (Roller Bearing Blocks) is designed for high-load, dynamic applications. These low-friction, lightweight blocks work well in backstays, cascades, sheeting and halyard applications.
They have black anodized aluminum cheeks, Torlon roller bearings, and Acetal ball bearings along with a washer to insulate the stainless steel head from the aluminum cheeks.
The shackle has a 6mm body and an 8mm pin. The ball bearing winch feeder is used for leading a line to a free winch.
