When you buy a new kitchen sink that is pre-drilled 3 holes, but you have another single hole faucet (no deck), you will find there will accumulate some dirt in other two unused holes, so purchase a deck plate will be the best solution for you. Made of selected 304 stainless steel, it will resist rust and corrosion. The hole is designed with the standard size, so it is compatible with most single hole faucet.
