ABSTRACT:
An improved floor drain plate assembly for closing the open mouth of a drain includes an apertured floor drain plate having slots and at least two jam clips. Each of the jam clips has a base and a pair of spaced apart legs. The assembly also includes bolts with an enlarged head and nuts for suspending the clips below the plate. When the clips are in place, one of the legs of each clip is jammed into a slot in the drain plate and the second leg can be forced by the tightening of the bolt and nut outwardly to engage the wall of the open mouth of the drain and secure the drain plate therein.
