3.6.3.313 screen door roller

Pictures are of the broken ones. What can I buy new?

I also need to replace this lower screen door roller, PAT. NO. 3.613.313. Did you get any feedback from the NJ quick learner who posted on 5/19/20 about how your 84-002 worked as a replacement? I have been looking for this part to replace several rollers. Thank you.

Happy to have found these posts online.
I too am trying to find replacement screen door rollers PAT. NO. 3.613.313
Did either home owner from Huddleston VA or quick learner from NJ try your 84-022 and report back yet whether it actually worked?
For now, I removed the original top roller and put it on the bottom left so the door will open and close smoothly. In other words screen door is only operating on three rollers.
Would like to purchase all new from you.
Thanks!

I can confirm that part #84-002 has the exact dimensions as the roller with the patent number of 3.613.313.

I came upon this thread because I was also looking for replacements for screen door roller PAT. NO. 3.613.313. Just placed an order and will try to remember to post an update regarding how well the replacement works.
