To install the window bracket to the window frame, you need to adjust the height or width of the window bracket by extending the length according to the height or width of the window. When the length is set, tighten the Adjustable Knobs (preinstalled on the window bracket) to ensure the window bracket is secured in the desired position. Use one or all three pieces of window bracket as needed.
