How would the Eco-Flec rolls go into corners and exactly fit the space? Should we send the exact measurement, or can they be cut and placed as needed?

You can easily cut our Eco-Flec Rolls to fit any space with a sharp utility knife and straight edge. If you are looking for a specific length, we do offer a custom cut version of this product that you can have cut to the nearest whole foot. With these rolls, you will get some extra material as with any rubber roll since no wall is truly square.
