Inventors:

Fan Zhang - Lake Barrington IL, US

International Classification:

E03C 1/23

Abstract:

An adaptor that fits inside of a drain tub insert. The adaptor has a central hub that connects to a radial flange at the top of the hub. The radial flange on the adaptor fits over the tub drain flange to provide a clean and new appearance. There are a plurality of compression clips extending out from the outer wall of the circular hub that engage the inner wall of the drain tub insert. This holds the adaptor in place within the drain tub insert so that there is very limited lateral movement and the adaptor is further securely retained inside the drain tub insert. The adaptor is designed to receive several types of stoppers such as a flip top stopper, toe touch stopper, and other stoppers in which the user raises a central post to raise and lower a resilient seal.
