"This triple Ball Bearing block offers friction free operation for lines up to 1\/4\". 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 shackle affixes to the loop top for easy installation on to your boat and fixed orientation of lines.The becket is fixed so be sure to splice the lines in to it if that is your intent. Ball Bearing Blocks meet the high performance demands of low friction applications with a two-stage bearing system. Fits lines up to 1\/4\". Precision moulded Acetal sheaves. Loop top with affixed shackle for quick installation."
