Thank you for your question, Bill! The RP61818 handle inserts are only used on a wall mount lavatory which has splines on the cartridge stem. The Lockwood collection did not offer a wall mount version so if the insert on your handle is missing or damaged the entire handle will have to be replaced. Please contact us directly if you need further assistance identifying which handle you will need.
Best regards, Edward
