Thanks for writing in. The roller with the off set mounting brackets that allow the roller housing to go deeper into the frame is no longer available. Now I am not sure, but see if you can notch out the location on the door where the mounting brackets are. Maybe you can "sink" the brackets into the frame just enough to clear the bottom track. Also take a look at the 81-128 roller used on Andersen patio doors along with the video below. See if this could possibly work on your door. |
