Once I decided to except that I was going to buy a door set that had to stay open when burning a fire, the choice was fairly easy Pete. I actually saw this set  at a friends house and was very impressed. Good construction, nearly 0 assembly, and a good luck made it a solid choice .  Although my fireplace opening did not fit any of the options for sizing, I purchased the large and made a very minor modification to the mounting. Can't wait for my sealant to dry so I can fire it up
