Replace Frames/ Repair frames

The outside of the roller will always face the same way as the panel you are attaching it to. If you are installing rollers on the outside panel (the panel closest to you when standing outside the bath/ shower enclosure) the outside face of the rollers will be facing you when you are standing outside the unit.

Outside Panel: Outside face of roller faces out into the room

Inside Panel: Outside face of the roller faces into the shower/bath  

If the rollers are installed correctly and the panels still do not slide easily, check to make sure there is no debris in the roller channels inside the top track of the shower door.
