HAND OF DOOR IS ALWAYS DETERMINED FROM THE OUTSIDE
What is the "outside" of my door?
For Exterior Doors: handing determined from the street or entrance side
For Interior Doors: handing determined from the hall or entrance to room or closet
If HINGE is on LEFT side of door, the door is LEFT HAND
If HINGE is on RIGHT side of door, the door is RIGHT HAND
*DOOR SWING is only specified for MORTISE LOCKS
Determining handing for door hardware is different than determining handing for carpentry (ordering and hanging doors). If you follow the standard carpentry rules for handing door hardware, instead of following our directions above, there is good chance you may end up with a lock that is handed incorrectly.
