The pictures might help you identify them. FWIW, the subdivision is Preserve at Wynmar.
The doors were installed early 2003 by the builder - Edgemoore. All of the windows in the house were made by Barber and Ross out of VA - they went bankrupt in 2007 or so. They also owned Rockwell Windows.
Based on emails I had with the builder about nine years ago -- fairly sure it is either a Barber and Ross or Rockwell patio door.
I don't want to lift the door out to check the wheels just yet - we need a warmer day to do that. I'll look at the video link that I have from Tim C and see how to remove the sliding door.
Any ideas on which rollers would work?
Thanks - Rob
