Marshall glass door replacement wheels

A quick learner from sacramento, CA 95864 says:
I need a new set of wheels for my Marshall Aluminum Product Meridian 10' sliding glass door. The wheels are very narrow and adjust from underneath on a very simple pivet system. The wheels are stamped "KILAIN" SYRACUSE,NY TORONTO,CA

Thank you for posting! Have you seen our 81-246 Roller Assembly? This appears to be similar to your old hardware. Please compare the two and let me know if you think it'll work as a substitute.

They look pretty close, but my wheels attach by one screw on one side and the other one is for the height adjustment. Your products photo is difficult to tell if it works that way.

Thanks for getting back to us. Could you perhaps take a few more pictures of your roller, then? I'd like to see some clearer images of it from a different angles. Maybe that'll give us a better idea of what you might have. Could you also give dimensions?
A quick learner from sacramento says:
I purchased the set of 81-246 per your request, but they're not the ones. I've taken new pics now with your wheels alongside on draft paper for dimensions. The width is correct, but the length is wrong and on mine one screw is for fastening and the other screw hole is threaded for adjusting the wheel up or down as you should be able to see from the pics, also my wheels are nylon.

Thanks for getting back to us. I'm sorry to hear that our 81-246 didn't work for you. Could you give me the distance between your screw hole centers? Maybe we can find an alternative.
