Determining handing when ordering door hardware is a bit different that how you determine door handing for carpentry (ordering and hanging doors). The reason being that when ordering hardware it matters which side the lock is on - where for carpentry it does not. If you follow the standard carpentry rules for handing, instead of following the diagram below, there is a good chance you may end up with a lock that is backwards. Please refer to the diagram below and if you have any questions, please give us a call at 877-611-LOCK (5625).

Follow These Steps:
I)	Stand facing the door on the outside - If it's a locking door, stand on the side of the door where you would insert a key (or unlocking tool if it would be a privacy lock). For interior doors you would stand on the side of the door you enter from - i.e. in the hall if a hall closet, in the bedrooom if a door opens to a bath, in the kitchen if a door opens to the pantry.
II)	If the hinges are on the left, it's a left hand door. If the hinges are on the right, it's a right hand door.
