(54) Drain closure


(57) A drain closure that has all the advantages of and none of the disadvantages of both hand and foot tub closures. A post (24) which is threaded into the bottom of the strainer body (10) receives a stopper (41) which moves up and down on the post (24) to open or close the drain. A metal spring (38) carried by the post (24) exerts a frictional force against the stopper (41) interior sufficient to hold the stopper (41) open an enhance its sealing ability when closed. The stopper (41) can be closed by hand or foot. The stopper (41) cannot be removed without first removing the stopper knob (60). Out of sight under the stopper (41) is an integral collar which receives an open end wrench which permits tightening of the stopper knob (60) to a point where stopper (41) theft is virtually eliminated.
