I called the factory to ask the very question. Their verbal answer was 150 pounds. Since nothing is in writing, I figure they haven't done any serious analysis or testing to back it up. So, I guess common sense rules. My Scamp
is pretty new, so the ledge under the window appears solid (and, as noted in an earlier post, carries the weight
, not the hinge). Another potential vulnerability I have wondered about is the bent carpenter's staple that is welded to the upright and catches the screw to support the front edge. Has anyone had any experience with failures there?
