Sliding door screen top hanging roller

A home owner from New York says:
For the life of me I cannot find a replacement roller for my sliding screen door. Manufacturer of door is unknown as I just bought this house and no identifying marks. This is a nylon Grover roller with a threaded 3/8 hub which when the hub is placed against the door for assembly it creates an offset. Nylon roller is 1" in diameter.

Please help me identify so that I can buy replacements for multiple sliders.

Thanks for posting. Look at our 84-013 roller with a built-in offset. This is used for patio screen doors. I think this is the best match we have, though keep in mind that it uses a screw and nut rather than being threaded.
