This is a bit of trivia for our Owner Builders,

One of the most common issues with metal door frames is working out whether the frame is right-handed or left-handed. There’s a simple way to tell. If you look at a door when it is closed and you can see the ‘knuckle’ of the hinge – the part that sticks out – on the left of the door, then you are looking at a left-handed door. If you want to hang a left-handed door, then you should order a left-handed door frame.

Likewise, if the knuckle on a closed door is on the right-hand side, that is a right-handed door. To hang a right-handed door, you should order a right-handed door frame.
