You should not need to shim unless you want to do it for extra support @ the top.
Hello, JD; I see that there are no instructions on how to install an exterior door with this kit, so I would recommend using it only on pre-hung interior doors! Sorry! But Home Depot could help you find all the hardware you'll need for hanging exterior doors! Good luck!
No! There should be at least 9 small screws and 3 drywall screws.
I haven't used it for exterior doors yet, only interior. I would check with the manufacturer web site to verify.
I really like these things... It makes installing a door easier. I often have no help or inexperienced help. So these things are worth it. I come back and install shims just because it makes the door rock solid.
If it was a prehung door and you are reinstalling, it would work fine.
Only if the wall is plumb. One would have to use a shim if the wall is not plumb. The leg that is used for side to side adjustments is meant to lay flat on a plumb wall. If you shim it, then the casement will be messed up. However even using shims will mess up the moulding. I would recommend to make your own frame and mortise it by hand to handle the out of plumb wall.
If you are placing the hanger on the door correctly, the large hole should fall directly over the center hinge screw. Once the bracket is in place and you have set the door, you have to remove the center hinge screw and replace it with whatever screw you are going to use. There is a Youtube video on the installation process. Just google "Quick door hanger youtube" I have used over 40 of these hangers and replaced the center hinge screw on all of them.
Yes! They work great! I used them to hang all my interior & exterior doors.
I had no problem with the casing being installed over top the door hangers.
