If you need to start from scratch, these aluminum strips allow you to build your own jalousie window frame 18", 24" or 30" tall.
The hardware is pre-assembled and ready to be installed along the insides of the rough window opening. The strip hardware is packaged in pairs (enough for one window), and includes one left side strip and one right side strip with lever operator and mounting screws included. Each is 1-1/8" wide.
It is designed for common vintage trailer size 4" high glass strips that are 3/16" thick. Glass is not included and can be ordered locally.
Because the indoor edges of the glass will tip into the trailer, insect screens may be difficult to fit over these windows. A spacer may be required.
Head and sill (top and bottom) sections are not included but are available and should be ordered separately.
These vertical strips cannot be cut to length.
