This disintegrating is happening to the rubber piece that covers the hinge, which is attached to the outer lid and main box by 10 screws and two metal plates. I have been fruitless in my attempts at turning up a part number or a dealer of a replacement. I'm sure I can find a suitable alternative at a hardware store, but I'd like to get some input, such as problems I might encounter (UV deterioration, etc.) Has anyone else had this problem? What was your solution?
