Quad is a simple and effective tap, designed for a wide audience but not giving up a decisive character. It is well-proportioned and fits the 35 mm cartridge. The spout is joined to the body through a curve that follows the lower part of it and connects to the side part of the body. The connecting surface follows the curvature in a harmonic way, allowing the flow of the mixed water, also solving the frontal “bottleneck” between body and spout that is needed for the mixed water flow.
