Used Chris Craft Commander small sliding window assembly. Approximately 24 1/2” overall in length, 13” tall and 1 3/4” thick. The frame is aluminum and has cosmetic corrosion to the exterior as noted in the photos. There is no structural corrosion, holes or other damage to the frame. All of the track “fuzz” should be replaced. There are no cracks or fogging to the glass and they slide properly in the frames. There are however some minor scratches to the glass from typical use. There is a screen however the screen material will need replaced. This window was removed from the head (bathroom) of a mid 1970’s Chris Craft Commander and stored for many years.
