ABSTRACT:
A drain closure that has all of the advantages of and none of the disadvantages of both hand and foot tub closures. A post which is threaded into the bottom of the strainer body receives a stopper which moves up and down on the post to open or close the drain. A metal spring carried by the post exerts a frictional force against the stopper interior sufficient to hold the stopper open and enhance its sealing ability when closed. The stopper can be closed by hand or foot. The stopper cannot be removed without first removing the stopper knob. Out of sight under the stopper is an integral collar which receives an open end wrench which permits tightening of the stopper knob to a point where stopper theft is virtually eliminated.
