Sizes and Handings
When thinking about installing prehung door kits. There are a number of things to bear in mind. Chief among these is the handing of the door. Stand in front of your proposed door and imagine the door opening towards you, The door is LEFT handed if the hinges will be on the left and the door will be RIGHT handed if the hinges are on the right. See the diagrams below for clarification. If you are unsure then feel free to contact us.
The next important consideration is the size of your door and the opening you need to leave for it. Each door size will have a corresponding door frame and kit size and a slightly larger opening in the wall. Consult the table below to determine the correct opening to get your builder to leave.
