3 1/4" - 1 3/8" part #A52
I haven't been in our Pennsauken facility since quarantine started, unfortunately. All of us have been working for home for the better part of the year. That location isn't a store, anyway. We're not able to service customers there. Our business is exclusively online.
All that aside, we have pictures of the back side of each roller mentioned on their respective store pages, along with detailed dimensions. I linked you to these pages in my last response. I recommend looking those photos over, they should contain all the information you need to confirm a match. Again, the offset is probably the most important detail.
As near as I can tell it is 3/4 diam but it is not as fat as some I have found locally.
Pictures attached of the sliding door hardware currently in use. I need a replacement for the 1/8 offset.
I'm afraid that your photos didn't come through. Could you please upload them again for me to review? You also mentioned that your wheels are fatter than those you've found at local stores, but you did not mention exactly how large they are. Can you also give me that measurement?
