I am confident, but of course the only way to be 100% sure is to compare our pictures and dimensions to your own hardware. There could be some wild chance that your roller base is different or specially altered in some way I cannot predict.
To remove the bottom rail, you will need to first lay the door on some saw horses or stable surface like a table. Unscrew the two bottom frame screw, then use a block of wood and hammer to gently knock off the bottom rail. If you aren't comfortable with this project, you may want the help of a local handy person.
P,
Thanks again for your assistance. I'm handy enough to remove the bottom rail. What bothers me is breaking the glass and, consequently, having no door or even a door manufacturer from which to obtain a replacement.
I'll think on this before buying or proceeding with the fix. After all, the rollers are working great after I applied a dab of Lithium grease to the bearings.
Best...
