How do I determine my door “handing”?
The handing of a door refers to the way it swings in its jamb. Exterior doors that swing into a house are called inswing doors, while those that swing out are known as outswing. For both inswing and outswing doors, the hinges can be installed on either the right or the left.
Believe it or not, a handing standard has not been established within the door community, so a “RHIS” or “right hand inswing” may be hung with opposite handings (hinges on opposite sides) from two different millworks. Drawing a simple diagram is a great way to communicate the handing you need, eliminating costly mistakes that add cost and lead-time to a project.
