French door installation doesn't need to be difficult. The first step in learning how to install double doors is getting both doors level off the floor. A good tip (which applies to any interior door installation) is to space the bottom of the jambs off the floor. This will allow you to make adjustment in the heights of the doors in relationship to each other. This principle applies to french doors
or even double closet doors
Once you have one door level, plumbed and squared to the jamb, it's just a matter of raising or lowering the next door to fit the first. This door installation process is simplified when using the very adjustable EZ-Hang brackets. Watch this video and see just how easy a french or double door install can be. You will get perfect door clearance and gaps between the doors.
