Door Swing and R.O. Question
 
1 Attachment(s)
I am replacing an old pre-hung interior door with a new one. I was thinking it was a 36" door, when I measured the r.o. it was 35 3/4, so I would need a 34" pre-hung door, is this right ? That doesn't seem to be a common size carried in the stores . . .

Second question, is the picture attached a right inswing door ?

You measure the door not the RO.
Stand in the room it's servinig, reach out to turn the knob, which hand are you using, that's the swing.
Residential doors swing into the room, commercial doors open out.

The door is for a closet, so I need to be able to pull the door towards me as I am standing in front of it, that is where I am getting confused.

Stand in the doorway with your back to the hinge, if the door swings to the right it is a right hung door, if it swings to the left it is a left.

The drawing you posted looks like an out swing not an in swing.

See, this is where I have so much confusion, maybe I am just over complicating it in my head. Is the picture a right inswing, or left outswing. . . or are they the same thing ?

The way Jim described it (back to the hinges) is how I’ve always known it.

The only time in-swing or out-swing come into play (when ordering) is if there’s a threshold (exterior door).

What you have is simply a "right hand door"

BigJim 01-04-2013 03:56 PM

From your drawing it looks like an outswing right hung, but it makes no difference if it swings in or out, that door is still a right hung door.

Okay, that makes it much more clear. So for this picture, I would get a 34" left swing door

I meant to type Right in the last post, not left.

Whether it’s right “hand”, “hung” or “swing” it’s all the same, just a difference in regional terminology.

ok.. everyones noticing the swing, im the only one that picked up on the fact that the rough opening is too small for a 34" door prehung. you need a minimum of 36" for a 34" to go in it. . always make the r.o a minimum of 2" larger than the size of the door itself. sometimes the r.o has to be 2 1/2" larger depending on how plumb the jack studs are and how thick the jamb material is

kwikfishron 01-04-2013 06:35 PM

Oh ya...that too.

OP said that he/she had a 35 3/4" RO which should be just fine "if" the framing is plumb.

You need to measure the opening not the door.
A standard 36" door, A new blank will measure 35 3/4" is typical.
The actual opening with the existing door removed. should be 39" or 3" bigger for the door jambs to be installed properly.
But yeah, a actual 36" door measures 35 3/4", the hole it goes into will be different.

woodworkbykirk 01-04-2013 07:26 PM

a 36" door is 36" .. even with the lean of the door if it has the bevel put on it your not going to lose that much width

if its a 36" bifold then its 35 1/4
