Using the hammer lightly tap the back of the screwdriver against the knockout plug repeatedly. Your disposer is ruggedly built to give you many years of trouble free service. Each knockout plug is typically stamped from the same type of material as the tube or hole it blocks. The name is derived from the fact that if the orifice needs to be used the plug can literally be knocked out.

Move the screwdriver around the perimeter of the plug tapping all the while with the hammer so you can cleanly remove the whole knockout plug. When knockout plug falls into disposer you may remove it or simply grind it up when the disposer is used. Before long the plug will fall back into the disposal unit. 3 3 8 inch 8 57cm kitchen sink stopper stainless steel garbage disposal plug fits standard kitchen drain size of 3 1 2 inch 3 5 inch diameter 4 6 out of 5 stars 1 157 5 39 5.
