Sir, I have 4 doors that need new rollers. Can you help me regarding removal of the old ones? I'm not certain how they should be removed or what type they are.

Based on this picture, I would say that you have a combination corner with wheel like our 84-011. To remove the wheel with corner, turn the adjusting screw to retract the wheel. The adjusting screw should be on the side end of the door. Remove the screen spline and screen wire and then tap the frame apart with a mallet at the corners. Then match up your corner size to ours to ensure that they are the same. If not, take some pictures of the roller/corner once its removed and we can work from there!
