Something that is so simple is a solution to so many frame/door opening problems. It all starts when a framer goes to install a door frame and installs it out of plumb & out of square. This can happen for so many reasons such as adding to much mortar or an over cut in in base/chair railing or just plain lack of attention. Now the symptoms of a door hitting the frame due to a sagging door or the latch bolt won't engage the strike due to sagging, the door hits the header of the frame & while all this is happening the very expensive hardware is being stressed to the max and never will meet warranty criteria.
