This is a quality air gap from Delta. It's much better than the cheap ones you'd buy at the home improvement stores. The Delta air gap has thicker metal and better looking chrome than the others. The trick to installing this is to set the plastic mounting assembly at the correct height- if it's set too high then the chrome cap won't cover it entirely. When you've got it set just right the chrome cap comes all the way down to sit right on the sink surface.
