I'm looking to purchase an outswing french patio door. The active door will be on the left looking at the doors from the outside. It would be on the right if I am looking at it from the inside. One sales associate told me to look where the hinges are and put your back to it. In my case, it would be a right hand outswing. Is this correct? Lowe's seems to do it a little different. This is for a Therma tru door.
