Sliding glass door rollers

Thanks for contacting us. I'm a little confused. In your first picture you have a pair of double wheel rollers, but the roller in your door is a single wheel roller in a different style. What did you need, exactly? 

We usually recommend sticking with what was installed originally, if you have a choice. With that in mind, the closest we were able to find was our 81-279. Their dimensions are a little different than yours, specifically the height. The 81-279 is 3/4" wide with a 1-1/4" wheel, but it's 1-3/8" tall. I would double check your height to confirm if this can work for you.
