This door replaced a standard exterior french door. We added on a sunroom years ago and the door has been "in the way" for years. Not enough room for a barn door, so we went with this french bifold. It opens up the LR better to the sunroom and isn't hitting the chair etc.This works for us because we rarely close this door. Easy to install and looks 100% better than the old door. I would recommend this for sure plus Wayfair was  less  expensive than other retailers.
