National Hardware - V794 1/8" Offset Sliding Door Hanger

Two of these hangers come with a kit that also includes a rail and two 7/16-offsets. The 1/8" offset is supposed to work for a front door of a 1-3/8" sliding pair. But they did not work for mine. The adjustment wheel on the front door stuck out so far that it scraped against the back door. I really like the adjustment wheel because it's much easier to adjust a door's height. But National Hardware apparently doesn't sell such hangers with less than a 1/8" offset. So I had to use a pair of 1/16" offsets from another company, with the old-fashioned screw/slot adjustments.
