Step-by-step guide
- 1Stand on the outside or key side of the opening.
- 2Identify whether the door swings toward you or away from you.
- 3Note whether the hinges are on your left or right from that position.
- 4From that same side: left hinges + away = LH; right hinges + away = RH; left hinges + toward = LHR; right hinges + toward = RHR.
Guide notes
Door handing combines the hinge side with the direction of swing. Always start from the outside or key side. A standard hand swings inward; a reverse hand swings outward. Confirm both the hinge side and swing before ordering.
