This is the top-end part of a faucet, including the prewash sprayer. It came off of a faucet from the Chicago Faucet Co., which froze on me in December. This portion works great with no damage. This would be a good addition to an existing faucet. You can see from the close-up of the bottom fitting that it can be adapted to any type of faucet. Great value for $50! oregon
