Sharp edge on bedroom divider wall is dangerous.

On my 2009 NC 22FB there is an exposed sharp edge on the wall corner that my wife has cut her arm on. Any suggestions on covering this other than duct tape?

Hard to tell from the catalog what that looks like. Is it a corner edge of the divider that separates the sleeping area from the rest of the trailer? If it's wood, you could try using a foam sanding block and rounding it a bit, then dabbing a little stain on it. Or you could check at a home center (Lowes, Home Depot) for a plastic corner molding that would give it a rounded edge and glue that over the sharp area. A photo would help.

Try a self-adhesive clear plastic corner that is often used with wallpaper. Should be available at any big box home improvement store...Don
