How to fix a door that hits the frame (Bending Hinges). Bending hinges to adjust doors is a practice that all carpenters should know when hanging a door and setting the closer. Having hooks on the back of the door for hanging clothes can make a door sag. Over time and weight it bends those hinges and naturally goes to the gravity side of things spreading those hinges out. Eventually the door will drag on the frame and will be hard to operate.
