I need to order the bottom track # 23-243. The two types of rollers you show are similar to the ones i have on the doors now. What is the difference between roller #23-199 and
#23-225 as they both show the same measurements, and look the same.

Thanks for posting! Good question. Our 23-199 has a standard convex nylon roller, while our 23-225 has nylon ball bearing convex roller.
