Prep faucets like this Trinsic Single-Handle Pull-Down Sprayer Prep Faucet in Matte Black go beyond the kitchen, to butler's pantries, morning kitchens and more. The pull-down spray wand comes free with a gentle tug and gives you total flexibility. The hose extends and retracts without friction points, fed by gravity. As you raise the wand to dock it, the magnet embedded in the spout pulls the wand precisely into place. So, unlike other pull-downs that tend to droop over time, MagnaTite(R) keeps your pull-down faucet looking picture-perfect. Delta's exclusive DIAMOND(TM) Seal Technology uses a valve with a tough diamond coating. InnoFlex(R) PEX waterways keep water inside the faucet out of contact with potential metal contaminants. This powerful combination brings you a faucet built to last up to five million uses. Only Delta faucets are equipped with Touch-Clean(R) soft, rubber nubbins that allow you to easily wipe away calcium and lime build-up with the touch of a finger.
