To determine which handing you need:
Standing on the outside of the door, 
If the hinges to the door are on the right, and the door swings inward into the room you need a RH.
If the hinges to the door are on the left, and the door swings inward into the room you need a LH.
If the door swings towards you, you need a right or left hand reverse LHR, RHR and I don't have those available.
