Hanging Prehung Door
Hanging prehung door is now easy! Hanging a pre-hung interior door in a rough door opening can be very difficult when using shims. The newest method of door hanging is using door hanging bracket kits. All screws included for roughly the same cost as a pack of shims. First time DIYs can now hang prehung doors like a professional. View the how-to instructional video below for perfectly hung doors. Available at most Home Depot locations, click for details!

Step-by-Step instructions for Hanging Prehung Door
FIRST.
The Rough Door Opening
A usual framed in rough door opening is around 2″ wider than the door that is to be hung (not including the door jamb/frame around the door). The reason for this is because most rough door openings are not square. The 2 additional inches leaves roughly 1/2″ on each side between the door jamb/frame and the wall. This additional space allows room for adjusting the door to level and plumb, even though the wall may not be.
Example: You measure a 32″ rough opening, you will need to purchase a 30″ pre-hung interior door to hang.
SECOND.
Draw Plumb/Level Line on Drywall
Start by making a mark roughly 1/2″ in from the rough door opening. Place a 4′ or 6′ level on this mark. Now make sure that the level is indicating perfectly level and plumb. Use the level to draw a line all the way down the wall. Make sure this line is perfectly level. You will be basing the hanging prehung door off of this “level line”.
THIRD.
Attach Door Hanging Bracket to the Frame/Jamb
Start by screwing a door hang bracket directly behind each hinge. Try to align the bracket’s clearance hole to the center screw in the hinges. This will allow you to replace that small screw with a longer screw in a later step for extra support if its a very large or heavy door being hung. Attach the other 3 brackets on the opposite side of the door frame at roughly 8″ from top, just above the door latch, and roughly 6″ from the bottom of the door.
FOURTH.
Screw into the Rough Door Opening
Place the door in the rough opening. Roughly center the door as best as possible in the opening. Now screw in the top hinge side bracket. Take note of which of the bracket’s reference notches the “drawn level line” happens to match up to. Screw in the next 2 hinge side brackets, making sure that the ‘”level line” passes through their exact same reference notches. The door is now hung perfect based on the drawn level line. When screwing in the other 3 brackets, simply make sure that the space between the door and the door frame/jamb looks consistent. The door is now hung.
FINAL.
Complete the Project
If extra reinforcement to hanging a door is desired, simply remove the center screws from each of the frame hinges. Remember you had aligned the bracket’s clearance hole up to these screws. Remove these 1/2″ screws and replace them with longer screws (roughly 2″). These longer screws will pass through the clearance hole and into the wall stud greatly increasing the door hung strength.
The door trim/casing can now be installed over the brackets as normal. The brackets will not interfere with the hanging of the casing at all. Hanging prehung door made easy.

Don’t hang a door without this!
We’re doing a lot of re-hab on our ’60s tract home. One thing my extremely handy husband was dreading was replacing the doors. We saw this kit, read the reviews, and got it with the bathroom door we’re replacing. What a GREAT idea!!! Our house was built on a Friday AND a Monday and the first owners, from whom we bought, understood Roman Coliseum living better than tract house living. So everything we do is magnitudes more difficult than it should be. But this door went in like a breeze because of this kit and its clear, easy directions. For a little over $5 you’re never going to find a better deal!
