Ronstan Series 30 Utility Ball Bearing Block - Single, Swivel Shack. [RF30100]

Description

Ball Bearing blocks use a two stage bearing system. Under medium loads, the Acetal ball bearings ensure minimum friction. Under heavier loads, where of the ball bearings would increase friction, the bearing on a polished stainless steel race takes over, maintaining low friction performance. The quality build allows for long life and low maintenance for the life of the block. The loop top allows you to use your own shackles to attach the block and ensures correct line orientation.
