The knob installs directly onto a square diverter valve stem measuring approximately 7/16 inch wide that protrudes through your spa's diverter cap. The internal square opening is sized at 7/16 inch to fit the stem securely.

Compatible with diverter valves that redirect water flow to different zones within your hot tub system. This universal-style handle works with numerous spa brands featuring black trim components.
