ABSTRACT:
An improved stopper arrangement is provided, for use with a remote stopper actuating mechanism having a mechanical lever system for raising a central post to which the waste stopper is attached. The improved stopper has a central spindle to which is attached the circular stopper disc by means of which the waste is sealed. A set of guidance vanes located beneath the stopper disc and serving to center it in the waste aperture is separably secured by locking means to the actuating spindle in variable height relationship to the stopper mechanism independently of the stopper. Special cranked tools provide access to the locking means, to preclude vandalization.
