I have a Patriot 5500 series door (71 1/2 x 79 1/2)and want to replace the rollers. I was trying to find disassembly instructions as the door will not lift up high enough to get past the lip to remove it. I think i need to remove the stationary section first but I am not sure. I will also need new bottom rollers which I believe are your number 81-156. Thank YOu

You typically do have to remove the stationary door first, yes. I recommend watching the video below. This shows you how we remove probably the most common type of patio glass door.
