Need 2 rollers for unknown brand patio sliding door at least 20 years old. Attached are the pictures. Wheel looks to be 1 inch diameter. Unit is about 2.5 inches long, but that is slightly expanded with the expansion screw. Wheel is flat not grooved. Getting this roller right is important because I have tried wheels from box store, and they can't clear the frame even when fully collapsed. Need this low profile roller
