I need two bottom rollers and two top roller replacements. My sliding doors are NOT mirrored. The plastic roller part on your photo looks different than the one I have. Again, mine is not mirrored. What do you recommend? Thank you. Roxane

Hi, Roxane. The Cox numbers you gave correspond to the following SWISCO parts: #21-717 is our 23-070, #21-767 is our 23-086 and #21-718 is our 23-081. It would be better to show us what you have, though, so we can identify them for sure.
