We're thinking of installing new sliding doors in a couple of closets; we'd like them to be wood with exposed, industrial-style ("barn-door") tracking hardware. Any ideas where such hardware may be available? The few places we've found only sell barn-door hardware suited for actual barn, etc. doors that are 1-3/4'' thick - we need something that is more suitable for residential doors, i.e. 3/4''. Any tips would be greatly appreciated!! Many thanks.
