Abstract: A unique pit board is designed for bowling alleys of the type having a pit conveyor assembly with a shaker mechanism to convey downed pins to an associated pinsetter, and comprises top and bottom shell members constructed from a synthetic resin material. The top shell member has a formed upper surface which is inclined downwardly toward a marginal portion to convey downed pins to an adjacent pinsetter. The bottom shell member has formed reinforcing ribs to rigidify the same. The top and bottom shell members are interconnected in an overlying relationship to provide a very rigid, lightweight construction. A mounting member connects the pit board directly to the shaker mechanism without any intermediate frame.
