I have sliding windows on the showers in my two bathrooms. On the outside their are three small rectangular slots on the bottom of the windows to allow any water to drain to the outside. Their are plastic hinged covers that cover these openings to keep insects out. They are approximately 1 inch high by two and a quarter long with two pins that hold them in. Does anyone know where I might get these covers as the sun wrecks them. The window manufacturer is out of business and the locals can not help.
