Thank you for your question! Our 13/14, 17, and 17T trim kits will work with any R10000 MultiChoice valve. UN versions have universal 1/2" copper and 1/2" IPS connections. BX indicates that it is sold as a single boxed item. The WS suffix means that the valve has integrated supply stops (With Stops).
For other suffix codes, please refer the Technical Specifications:
