A. Faucet handle selection can be very difficult if a customer doesn't know the name of the manufacturer of their faucet (stem) and/or if they are unable to remove the old insert without damaging the spline pattern so that they can count the splines (points) on the stem correctly. The spline pattern (point count on the stem) is the necessary part for replacement. The Internet is wonderful and we have many thousands of customers but with faucet handles this might be a case where you are better off going to a good local plumbing supply store with your stems or faucet.
