This item is a Black Handle used on a Waterway Waterfall or Neck Jet control only.. Note: this looks similar to an Air Control Handle but they are different.. The main thing is the Square part that slides on the valves stem it is about 3/8" wide... The Air control is much smaller.. We offer this in different colors as well.. 

Some have 602-4330 cast inside the handle but that same number is found in all colors..
