Dear G Clarke,
Thank you for your inquiry! Yes, the Delta Cassidy Lavatory handles H297 will fit and work with the Delta Classic lavatory 2523LF-MPU faucet. All of the handle sets of our Delta Lavatory faucets are interchangeable with all of the two handle faucets, due to the Delta stem assembly shape, that they tighten to.
