We needed this fireplace door for a big masonry fireplace.  Although we had to extend the door to the maximum width and height, we were able to add fireproof insulation to make it fit well and stay relatively air tight.  That saved us hundreds of dollars by not having to get a door custom made.  The quality of the door was better than expected for the price, and it is beautiful.  We like the screen doors opening like doors instead of curtains.  Overall, this has been a great addition to our project.
