I'm afraid I'm not sure what you mean when you reference a 12" header and sill plate. If you're referring to the base track of the hinge then we unfortunately only carry 10" and 14", which you've already reviewed. If you can send us some photos of your windows and hinges for us to take a look at, that might help identify what you're working with and whether these parts can work. |
