+1 I butressed all the stressed parts inside the door with epoxy. I now have a very strong door, especially around the hinge area.In my case the plastic that the hinge goes into broke. It's way too fragile and small for its purpose. Since I'm a boater I knew about Martex which is a two part marine epoxy that is as strong as steel and just mixed some up, put it on and drilled a hole in it when cured then put the parts back on. The plastic hinge area that holds the metal is now two or three times the mass and size of the original and it's been fine. Any boating store has it in small packages...MarTex. Boater's World and places like that.
the door is not substantial enough at all
