The Extension Jambs: The Professional Doorjamb

With the invention of the door came a new and beloved part of humanity - privacy. Though interaction is an essential part of every civilization, so too is the need for time alone, an area to call one's own. The door was the perfect way to ensure that was possible. However, a door cannot stand on its own. It requires support. That comes in the form of a door jamb. Often overlooked, ignored, or underappreciated, the door jamb plays a very important role in every home.

Installing a door can be a difficult and daunting task, for most of the homeowners or even novice contractors. Installing the door correctly, can make a big difference on how long the door will take before it actually starts rubbing against the kikgard metal doorjambs.

Professional door hanging advice can only be given out by people who have dealt with and solve these problems in the past and now know how to prevent them in the future.

The extension jamb is a piece of wood that can be nailed on one side of the door jam, to make it a little longer, if necessary. Here's an example of what I'm talking about: you go down to your local home improvement center and buy a pre-hung door and the doorjamb width it is 4 1/2 inches wide.

This doorjamb is made for a 3 1/2 inch wide rough framed wall, with one sheet of half inch drywall on each side, giving us a 4 1/2 inch wide wall, which the new doorjamb will be covering.

Now what if, you're going to be using a 2 x 6 wall or a 2 x 4 wall with 5/8 inch drywall on each side or a 2 x 4 wall with plywood on it and then half inch drywall on each side. Your standard doorjamb will now need to be wider and this is the purpose of an extension jamb for crime prevention.

Install the door even to one side of the wall and then you will install the extension jamb on the other side of your new doorjamb.
