From the Manufacturer
If you have ever had to notch cut a skirt to fit an existing profile, you know what a difficult and time-consuming layout job this can be--and how easy it is to make a mistake. The Stair Genie simply transfers the stair profile--any stair profile--directly onto the skirt material. It completely eliminates the need for complex measurements, templates or figuring of any kind. Your layout time will go from hours to minutes with less error. Complete with parallel edge gauge, and easy to follow instructions and fitted case.
