You guys are crazy! I have 3 sets of double French doors on the back of my house, which for us is the only doors we access every day. They are very surcure! But mine are NOT 2-18" in a 36" door space(my utility is though). I'll talk about utility doors later. My 3 sets double doors are 2-24"(each). One door on all 3 pairs, on the inside side of the door, has a top and a bottom latch lock and makes this door stationary. When the opposite door (passage door) is open you can see these two brass locks if you look up and down on the inside of the door where the cylinder catch latch hole is. They lock inside the molding above the door and into the threshold on the bottom...Was not unaffordable at all. I also have one double deadbolt lock on all the passage doors on all three sets of double French doors. It's a personal preference to have a knob on both doors of one set- one can be a dummy knob. They are very convenient when needing to get oversized furniture inside or out. Just open the passage door and unlatch the two brass latches, on top and bottom of the stationary door land open them both, it's that simple. However, when you close them you must latch the locks down, if not anyone can push them open even if the passage door is locked. When all 3 sets of my doors are open(makes up my back wall) it lets the outside in. They are also great for entertainmenting as my doors or in the keeping room where some like to gather to watch the game and use the restroom but still be a part of the outside party too. The original Postee is wanting this look above, but she only has a 36" max space opening drawn on the plans and can't make it larger(if I'm correct?) I see this is an OLDER blog, but I felt I needed to add my two cents just in case others read these just like I am at the moment, the photo at bottom are of my house double doors, the 3 set is to the left of the picture there is a hallway that they fall into.

Thank you HomeSealed. I will take your advice. I don't really care for the wood doors. I was considering them only because they're solid. I would have wanted to paint them so the refinishing alone would have been time-consuming. We can't afford to pay a professional installer. I'm curious about why the doors would be so difficult to install. Would that statement apply to all used doors? If we bought new doors and intended to install them ourselves, would it be easier if we got pre-hung doors? I thought fiberglass would be nice but I've read that a good quality metal door is better than a cheap fiberglass door. Any recommendations on what material is available at a reasonable cost? How much should we expect to spend for decent quality doors that don't have windows? Our opening is 72 x 80".

Thank you. That makes sense and the multi-point on the 2nd door does sound like what I'm wanting. As it turns out the multi-point lock this manufacturer uses, won't work on the secondary door. I guess all locks are not created equal and this particular one doesn't bolt into the head jamb and threshold. Regardless, you help me better communicate my needs to the manufacturer.

Also I would not be bothered with centering the front door. Show a full elevation picture because it was obviously offset for a reason. Symmetry often times is overrated.
