Handing of the Door
The “handing” of a door refers to the direction that the door swings. It is important to know the correct handing of your opening when ordering Doors, Frames, Exit devices, Locksets, or other hardware. The hand of a door is determined from the secure side of the door. The term “secure” means the side from which you initially unlock and enter.
First, start by determining if the door is to be opened by pushing away from you or pulling towards you? Which side are the hinges on as you are viewing the door?
- If the hinges are on your Left side, and the door is pushing away from you, it is a Left Hand (LH) Swing.
- If the hinges are on your Right side, and the door is pushing away from you it is a Right Hand (RH) Swing.
- If the hinges are on your Left side and the door is pulling towards you, it is a Left Hand Reverse (LHR) Swing.
- If the hinges are on your Right side and the door is pulling towards you, it is a Right hand Reverse (RHR) Swing. Outswinging doors are reverse bevel doors.
Double doors usually have an Active Leaf and and Inactive Leaf. Again from the secure side of the door opening, as you’re viewing the doors, do they swing away from you or towards you?
- If the door on the left side is to be active, and the door is pushing away from you, it is a LH Active Opening.
- If the door on the right side is to be active, and the door is pushing away from you, it is a RH Active Opening.
- If the door on the Left side is to be active, and the door is pulling towards you, it is a LHR Active Opening.
- If the door on the Right side is to be active, and the door is pulling towards you, it is a RHR Active Opening.

Double doors will sometimes have both door leaves active. This means either door will work independently of the other. An example of this is doors with push and pulls, where neither door is locked. You would hand them as RH/LH or RHR/LHR
Some double doors (usually across corridors) seem to be going in opposite directions. These doors are called Double Egress. If you look closely, their handing will be LHR/LHR or RHR/RHR. Usually both door leaves are active.
Whenever there is an exit device on your opening, it is a reverse bevel door (RHR, LHR).
