I think you have an older model of our S795-27, one that uses an older and outdated rating system. I recommend weighing your sash on a scale to confirm which S795-27 stamp option will work best for you. I also recommend purchasing our 15-195B open cam shoe separately, since this appears to match your original. You can swap it out once you get them, it's very easy. The video below shows you how. |
