The UnitedBuilt BC2403-K adjustment knob is a replacement external component for BC2403 and BC2403H spray head valves. It is the knob used at the valve adjustment mechanism, not a complete spray head valve or hydraulic actuator.
Selecting the individual knob lets you order the component needed for a knob-specific repair. Inspect the surrounding adjustment parts before ordering so that damage to the spray band or attachment point is not mistaken for a knob-only problem. Match the valve model and existing part rather than choosing a general-purpose knob by appearance.
