Hanging bracket

The picture of the bracket on the blue chair is broken on the bottom. You can see where the track is supposed to sit on the installed picture. I measured the end to be 1" but I can't find an exact match on your site. I can't find hanging brackets anywhere but I can't imagine you're the only manufacturer. Super frustrating. I don't love being handy, but I do what needs to be done!! That's why I'd prefer to stay with the hanging bracket so at least I don't have to level them. :)
