Ironbob,

I have the Edinburg Large doors (ED5412) that were purchased earlier last year. The unit itself is 43.5" wide x 31" high. It also comes with a riser that can be installed to add another 1-3" of height (I can't remember its exact size as I did not use it). I just re-measured my actual fireplace opening and it is 36" wide by 25.75" high. The doors also come in other sizes (e.g. small, medium, large, etc.). Do a search at HomeDepot.com for Edinburg to get the product information on the various sizes. Overall the doors are well made, durable, and look great. I am very pleased with them and at the price I got them for last year, they are a steal of a deal! Even the regular price at HomeDepot.com of $270+free shipping is a great deal! Hope this helps!
