Caster for sliding patio door, Anderson

A home owner from Columbia, MO says:
I am looking for a set of replacement casters for our sliding door. As you will see in the pictures it has a number 7116A-5 on one side and the letter B on the other as well as patent info and number.

I think you might want to consider our 81-128. Your picture shows what I believe is just the inside portion of the 81-128 roller unit. Check it out and see what you think. You may want to remove the outer housing from your door just to make sure, though.
