Patio glass sliding door

Hello I did manage to remove the sliding rollers they are attached by two screws at each end. And one adjustment screw goes into the side. Attached are photos but I did not take any of the rollers attached to the door. I could not remove the wheel as it is in a steel case. Each wheel can pop in or out like a tandem style. Hope you can help.

Yes I was thinking the same and wanted to ask what the return policy is if we are misstaken?
