Install the ceiling threshold

  1. Lift the ceiling threshold up to the top of the doorway.
    Note: Slant the threshold and lift the right edge up first. Make sure that you do not scratch the door frames with the threshold.
  2. Slide the threshold outwards against the door frame.
    Note: Make sure that the side frame seals are not between the threshold and the door frame. Neatly cut the side frame seal to the correct length, if needed.
    Note: Make sure the side frame seals and the threshold seal do not overlap. Neatly cut the threshold seal to the correct length, if needed.
    Note: Make sure that the protective plastic on the aluminum frames is not under the threshold. Peel back further, if needed.
  3. Install the ceiling threshold with black 5x30 screws (4 pcs).
