HotSpring Spa Hydromassage Jet Face Warm Gray. There are two tabs inside this jet face that if pried up slightly, you can then turn the face counter-clockwise a quarter turn to remove it from the spa. This jet face provides the platform for the directional and rotating jet nozzles that insert into the center. Once the jet face is locked into position it can be rotated a quarter turn to adjust the strength of that jet.
