Find Your Window Code
Every roof window carries a code on an ID plate inside the frame. That code tells us the exact size, so your blind is made to fit with no measuring.

Where is the code?
- 1. Open the sash. Swing the window open so you can see the top bar of the opening frame.
- 2. Find the ID plate. Look for the metal plate or label on the sash.
- 3. Read the code. The window type comes first (for example GGL), then the size code (for example M06).
