Two-handle (duo-handle) faucet 1500-600, manufactured between 1990 and present. These are all ceramic models with a 90° rotating mechanism. If your handle rotates further and is not ceramic, it is from before 1990 and we need to investigate this specifically for you. Please contact us with some photos first.
It's important to determine which part of the drawing applies to you. First, you need to determine when the set was delivered. If you're unsure of the age, we'll need to determine which internals you need in a different way. This is actually only visible if you remove the control knob. The rod that holds this handle is different on models from 1990-1996. If you remove the handle and the spindle looks like the one in this photo, then you have the type. 1990-1996

Later models have a different internal mechanism, characterized by a slightly longer spindle. Longer spindles are also available, but these are extended versions. Information about these can be found with the VR697K and VR698K internals.
