When pre-hanging a door, there are some doors that are considered handed. This means depending on how they are oriented, their special features may be visible or useful. When ordering a handed door, it is important to specify if the specialty side is on the hinge side or the stop side.
The term stop side comes from interior flat jambs that require a piece of material to stop the door from swinging too far and pulling on the hinges. The stop material is applied on the opposite side of the hinge. Not all jambs use a separate piece of material. Some jambs have a built in stop, but the same concept applies.
Hinge vs Stop Side
The side with the hinge is the Hinge Side while the side with the stop is the Stop Side. It is a good time to also mention another term that is often mentioned when it comes to units. The strike side references the side with the door knob. It is called the Strike Side due to the strike that is installed on the jamb into which the latch sits.
A great example of a handed door is a louver door. The orientation of the door is associated with the blind side – or the side in which you cannot see into the next room or space.
In addition to noting how the specialty door should be oriented, you will need to identify if the door will have a left or right hand swing. The stop or hinge side have no impact on which way the door needs to swing.
