Everbilt sliding door hardware set.
Anyone ever install one of these closet door sets from Home Depot. It's marked on the package that it will work for 3/4" to 1 3/8" doors. I tried to install one for a customer today on some 1 3/8" Luan doors. It was some old doors where there had been a sliding door tract there already. I put up the new tract and them put the rollers on the doors and went to hang them and it wouldn't work. I took the rollers off the doors and put them on the tract and there was only 1 1/8" space between the rollers. There is no way those could have been used on a door thicker than a inch without mortising the hinges into the door on the back.
