Whew! It is a 36" door and my back door is same size.
Got worried for a second there, wouldn't surprised me too much if the contractor cut corners on my doors too!
I feel better knowing it won't be an issue to get in though I'm sure a tight fit. I was kinda hoping it wouldn't, give me reason to buy a 4-2-1 exhaust right off the bat!
may do it anyways, I know it'll only be a couple weeks and I'll be placing that order anyways!
