These glass doors were easy to install, and it took us less than an hour to go from box to beautiful. The clamp system makes it easy to fit the doors to any fireplace opening within the size range listed on the website. Instructions are easy to follow. As others have said, these contemporary doors change the look of our room and are an high-value upgrade from our old chain link screen. In our last house, we paid three times this price for custom doors; and while the custom fit is trimmer, I'd never do that again. These look perfectly good!
