Hi, I have a folding door that I custom ordered about 7 years ago. It is usually in open folded position. Because my first floor is a mostly open floor plan, sometimes we have competing TV's. So we installed a folding door that is oak and frosted panels. Unfortunately the sliders that attach the door to the runner have broke and they are plastic. (I think the dog pushing open the door cause them to break). The manufacturer, who was in Florida, is out of business. I found a company that I believed had purchased their inventory, but the company could not help me and they told me their is no industry standard to folding door hardware. Thus I can not get replacements. Any ideas, or if any contractor can assist I would appreciate it. I am in Central Mass
