Measures 3" in diameter with a low-profile 1/4" inch thickness, and a 1-3/4" standard sized center opening, providing a compatible fit with most sinks and sink drains. Slight elevation of sink bowl also allows for easier cleaning.
Ring includes clear, no-show-silicone o-ring seals inset into the grooves at the top and bottom of the mounting ring, for a snug, stable installation.
Please note this ring is designed for use with round sink bowls for best fit. May be used with oval or square shaped sinks, but may require silicone to fill any small gaps between the sink and ring.
