Thank you very much for assisting!
Our house was built in 1999. One of the wheels on our sliding glass patio door broke. I took it out, but I am having trouble finding the correct replacement part. I am not sure what brand the door is or if that matters.
Please see included pictures. There is another metal part still in the door that this cartridge attaches to, but that is screwed into the door frame with the screw head not facing down (so I can't remove that piece without taking out the door). Any assistance would be greatly appreciated.
