Each roller assembly carriage to preferably include a roller journaled onto an axle fitted through the carriage, with a lower edge or side of a section of the glass, or the like, maintained between upper sides of the carriage as a casing. The roller axle is arranged to fit through the channel flanges transverse slot, but will engage the undersurfaces of the flanges, to block travel of the roller out from between the channel flanges, should an attempt be made to lift the sliding door out of the lower track. |
