Manhattan shower door roler, hinges and stopper

Thanks for writing in! I'm sorry to say that I do not recognize the part in the last photo. My I see a photo of it removed from the door?

In regard to your shower door rollers, they look like they could be our 10-075 Lateral Angle Door roller assembly and 10-076 Angle Door roller assembly. To confirm that these are the right replacements, take a look over the dimensions below.

Dimensions for 10-075

Dimensions for 10-076

The bracket at the bottom of the door appears to the be the 10-079 Right Bottom Retainer. The left handed retainer is part 10-078. Again, look over the dimensions to confirm that these are the right fit for your door.

Detail of 10-079.

Thanks for the photo and for clarifying its function. Unfortunately, I was not able to source a suitable replacement for this shower door stopper. You'll need to visit a local hardware store to determine if they might have a replacement that will work in its place.

I apologize that we cannot be of assistance with this part of your repair.

Please let me know if there is anything else I can assist with.
