Genuine SAM table part. The ‘O’ ring holds the ball runs together that guide the balls from the gully boot into the centre tray. They can become worn over time, especially where fixed to the centre tray with a starloc washer. when not properly secured the rings can slip down the runway or the whole runway jump out of position under impact. This causes balls to fall inside the table and put the table out of action. A small but vital part of a SAM pool table!
