I've recently used those - not that brand, but like it, for wood and MDF doors, but not glass. I've put plastic rails on the bottoms of some doors, not other. Or small metal buttons. Depends on how heavy the door is. As for face frame or Euro - it's just a matter of how you want to hide the track, or drop it into a dado, or leave it proud.Thanks, this is helpful, I'm wondering if something like this exists for face frame cabinets and if anyone has used these?
