This front wing window is for 1970-83 Airstreams. This window is single pane glass. You will receive the window frame with glass pre-installed. Glass is not available separately. 

You will need to remove the old frame from your trailer and install this one instead. If you have the interior wall of your trailer out, you should buck this rivet in. If you leave the interior wall in place, you will use Olympic Bulb-Tite rivets in the 5/32" diameter to install.

Keep in mind that you may have to do some minor trimming of the aluminum shell to get the new window frame to fit in your old opening. Measures 25-3/8" tall and 15-1/2" to 16-1/4" wide.

You will need a splice bar to connect to the center front window. You can reuse your existing splice bar or order a new one from us if yours is missing.
