use caution when buying this part! Measure your old one first. older sinks list the same part no in their parts breakdown. the older ones measure 1.550 in diameter. The Chicago faucet supplied part measures 1.460 in diameter. It will not work in an older sink, such as a widespread lavatory shampoo sink. Attempts to return it were unanswered by Chicago faucet! It is a well made Kohler brand product though.
