Window Roller Needed

Thanks for writing in. I'm afraid I'm not sure if we have an exact replacement for this roller. The 87-160 is the first thing that comes to mind, but I have no idea if that's what you need without knowing the dimensions. Please tell us the width, length, and height of the nylon housing, as well as the diameter of the metal wheel, and we will see what we can find for you. Many thanks.
