Need to replace these rollers

Have you seen our Sliding Patio Screen Door Roller Assembly, with steel ball bearing wheel, 84-071 ? Please compare your measurements to ours to decide if this is a good match for you.

Hi there, 

I would necessarily say they either one is better than the other it is just what you prefer. The nylon wheels are said not to rust as easy and can be a bit quieter when rolling across the track, but it really is personal preference. 

Let us know if you have any more questions!
