Shower door parts help

Thanks for reaching out. It does appear that our 10-058 is the closest replacement match to the roller kit you are looking to replace. This kit used to have a bottom "hook" guide like your original, but the manufacturer changed the design (please see the diagram below for reference). While the design does differ, it should still be a suitable replacement.

New parts compared to old parts

To confirm that this is the correct replacement carefully review these parts to determine if this kit would be the right fit for you. Also, keep in mind this part is only available in gray.
