The walk door feature saves indoor building space and keeps
  all openings in one location. We build the walk door framework
  into the Door. We use factory aluminum or steel walk doors of
  your choice. All walk doors have a keyed cylinder lock. Also
  available is keying multiple doors with a master key. We offer a
  16" x 16" window within the walk door. Also we can paint the
  walk door to match the building.
