Pfister model # 001-3110 and # 01-341 are a complete Tub and Shower set, which include rough in valve and trim. Rough in valve included in model # 001-3110 has no stops, and model # 01-341 comes with screwdriver stops. The stops on a valve allow for the water supply to be shut off right at the valve. This allows the homeowner or plumber to maintenance the valve without having to shut the water supply off to the rest of the house.
