This specialty drain and strainer assembly fit sinks with drain openings ranging from 2" to 2-1/4" in diameter. These unusual 2" drain openings are commonly found in utility, bar, wall-mount, and prep sinks as well as some European sinks. Each drain assembly features a removable top grid. This grid prevents smaller debris from entering the drain and can be removed to clean the bottom of the drain as well as to promote quicker sink emptying. The outer flange diameter is roughly 3" in diameter, the inlet is 1-1/2" OD, and the drain will fit a sink with up to 1-1/2" bottom thickness. Available in a range of finishes to match our wall mount faucet offering and provide a fully coordinated look.
