Two-hole centerset wall-mount kitchen sink faucets install into walls or vertical surfaces that have two centered holes that are 4" apart when measured from center-of-hole to center-of-hole. Wall-mount faucets save counter space in tight or busy kitchens. These faucets combine the hot and cold water supplies to come out through a single spout and provide running water for dishwashing, cooking, cleaning, handwashing, and other tasks.
