Thanks for writing in! The roller you have attached to your door appears to be our 23-098 Concave Mirror Door Roller. The track compatible with this roller is our concave style tracks. Since you are looking for a length of 47-1/2" I would suggest our 23-271. It is 59" so you'll need to cut it to size.

We do have a shorter track, part 23-270 but it is only 47".

Take a look at the dimensions below to see if this will work as a replacement.
