Dual-lever-handle four-hole widespread with sprayer deck-mount kitchen sink faucets have two L-shaped handles that users pull toward or push away from themselves to start or stop the flow of water. Each handle is operated separately to control the hot and cold water supplies and adjust the water temperature. They also have a sprayer that lets users direct a spray of water to any area of the sink. The hot and cold water supplies join inside the spout to provide water for dishwashing, cooking, handwashing, and other tasks. Four-hole widespread with sprayer deck-mount faucets install onto kitchen sinks or counters. They require three holes for the faucet unit, and the outermost holes should be 8" apart. They also require a fourth hole for the sprayer.
