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.
