Bathtub Overflow Drain Plug

The Bathtub Overflow Drain Plug is sized for overflow pipes with a 2-inch threaded nut and cap and a 1.875" (1-7/8") inside diameter. This should be a slight press-fit into the pipe with the flat side up. This plug increases the water height by over 1-5/16" and yet still has a large enough opening to allow over-fill protection.
