American Standard toilets with inset center tank lid
A note about American Standard toilets from the 1940s & 1950s with inset center tank lids: Our seats will fit the mounting bolt holes and bowl size. However, when putting the cover (top portion) and rim (where you sit) in the up position, the cover will not fit into the recess as well as the original seat models did. In some cases, the seat may not stay up by itself. A possible resolution is to slide the tank lid back all the way and check that the toilet is level, not tilting forward.
