These are concave rollers — the tread is grooved so the wheel sits down over a rounded or raised track rail and holds the door centred as it runs. Match the profile to the track you already have: a concave wheel will not track correctly on a rail shaped for a flat or V roller. The roller reference guide in the gallery shows all six profiles side by side so you can identify yours before ordering.
