Handing (door)
How a door is “handed” — which side the hinges are on (left or right) and which way it swings (in or out) — described from a set viewpoint so the factory builds it to fit.
What it means for you
Get this wrong and you get a door that swings the wrong way or won't take your existing hardware. It's the one spec you and the salesperson must agree on precisely; a good rep confirms handing on-site, not from memory.
Where you'll see it
A required field on every door order.
Also sold as: hand of door · inswing/outswing
