Door swing & door handling

Common swing doors can have four door swing directions: Right Hand Inswing (RHI), Left Hand Inswing (LHI), Right Hand Outswing (RHO), and Left Hand Outswing (LHO).

How to determine door swing direction

Stand outside the room, i.e., in the hallway. If you use your right hand to grab the door lever (or door knob), it's a right-hand inswing or outswing door. If you use your left hand to grab the door lever/knob, it's a left-hand inswing or outswing door.

Frameless doors with concealed hinges

The following table shows door handling for frameless filomuro doors with concealed hinges (such as Anselmi or Tectus).

Note: Sometimes you'll see architects in their door schedules mark a right-hand inswing door as RHI or RHIS; left-hand outswing as LHI or LHOS; right-hand outswing as RHO or RHOS; and left-hand outswing as LHO or LHOS.

Common methods for determining door handling

The US door industry uses two common methods to determine door handing (the direction that the door swings):

1. Outside-Facing Method — You stand outside the room or building, facing the door. (Angelbau uses the Outside-Facing Method for our frameless flush-with-the-wall doors.)
2. Hinge-Facing Method — You stand with your back to the hinges. For inswing doors, if the door swings inward to the right, it is a right-hand inswing.
