Handing

Sometimes it is required that you know the "handing" of your door handle to indicate which direction the handle turns or operates. Handing must be determined for each door. You often will need to know handing if you are ordering a door lever, an entry door handle, or a mortise lock set.Handles are either "Left Hand" or "Right Hand."To determine handing:1. Stand on the outside of the door. For instance, if you are getting the handing for the front entry door of your house, stand outside of the whole house; if you are getting the handing for a bathroom door, stand outside the bathroom; for a bedroom, stand outside the bedroom; and so on.2. Facing the door, see what side the hinges are located. "Left Hand" = The handle is on the left side of the door. "Right Hand" = The handle is on the right side of the door.That's it!! Ignore which way the door swings.Use the diagram below as an additional aide to determine handing.
