Installation Note
This handle is the "New Style" volume control design and is intended for valves manufactured primarily after the year 2000. It covers the flow mechanism (not the temperature control). Before seating the new handle onto the cartridge spline, ensure all debris or old limescale buildup has been safely cleared away to ensure a tight, flush fit.
