How do you determine if a door is Right Handed (RH) or Left Handed (LH)?
When you purchase levers, keep in mind handing. Doors can be left handed or right handed.
To determine the handing of a door, face the outside of the door as though you are entering a room.
If the hinge is on the left, the door is left handed. If the hinge is on the right, the door is right handed.
Some handles are reversible, which mean they are positionable in either the left hand or the right hand configuration.
