Williams – WPC 6-Ball Trough Upgrade – A-16809-M
Totally redesigned trough assembly. This trough has a unique rail system so it will not jam if a light bulb or screw goes down the entrance hole. It just falls through the rails. The stainless steel rails are non-magnetic so they will not magnetize over time. It includes a slide mechanism to stop the balls from coming out when doing maintenance.
