Designed to capture the essence of a bygone era, Devonshire¬Æ faucets and accessories bring a versatile, traditional style to the bathroom. This shower trim includes a showerhead with Katalyst¬Æ air-induction spray. By infusing two liters of air per minute, Katalyst¬Æ delivers a powerful, voluptuous spray that clings to the body with larger, fuller water drops. Pair this trim with a Rite-Temp¬Æ pressure-balancing valve, which maintains your desired water temperature during pressure fluctuations. THIS NEW K-TS396-4 TRIM REPLACES THE EXISTING K-T396-4 TRIM. THE NEW TRIM IS IDENTICAL AND INCLUDES TRIM ADAPTER KITS FOR BOTH RITE-TEMP K-304/K-2971 HIFLOW AND THE NEW K-8304 SERIES VALVE. Pressure-balancing diaphragm technology maintains outlet temperature within +/-3 degrees Fahrenheit during water pressure fluctuations. Provides temperature regulation and automatic anti-scald protection. Single handle controls both on/off activation and temperature setting. Includes faceplate with ADA-compliant metal lever handle. Includes single-function 2.5 gpm (gallons per minute) showerhead with Katalyst¬Æ air-induction technology. Showerhead features MasterClean‚Ñ¢ sprayface for easy cleaning. Includes shower arm with flange. Coordinates with Devonshire¬Æ faucets and accessories. Trim set requires valve to complete installation (sold separately).
