How to replace sliding glass patio door with pocket door ,LONG

We're building an addition to the house. One exterior wall will be shared. Access to the addition will be through an opening which is now a 6 foot wide sliding glass door (on a load-bearing wall).
I would like to replace this sliding glass door with a 3 foot wide pocket door.

The alternative is to have no door, only a 3 foot opening.

If I remember correctly from what I've read, the rough opening width of the pocket door needs to be twice the width of the door plus 1 inch, in this case 73 inches. Is this correct? How do I know what the rough opening is now, without removing anything from sliding glass door frame? That is, is it likely that the rough opening is sufficient already?

Also, in a reply to a question about installing pocket doors, sierraeast wrote
"The track should also NEVER be attached to a header in a weight bearing wall.
A secondary header should be installed with about a 1/2 inch clearance below the structural header. "
Since there have been no problems with the sliding glass door in 30 years, should I assume that a secondary header is already installed? (I know, don't assume anything, but I need to ask).

Thanks in advance for any advice or suggestions. You folks are so helpful.

Not sure what your plan is for the addition but have you considered french doors with or without privacy glass? This would ease the pain of framing in 3' and make nice entry to the addition!

saskatchewan girl,
Thanks for the suggestion.
I don't want swinging (or bifold or accordian) doors because I want to maintain the same door/access schemes as in the existing house. Also, these types of doors would interfere with wall space and/or other doors.
The addition includes a laundry/utility room, foyer, and master suite.

--should I assume that a secondary header is already installed?--

No. A sliding glass door runs on a track on the floor and a pocket door on an overhead track.

Hendricus,

What sort of idiot would frame a load bearing wall for a 6' opening and not put a header in? In 30 years there should have been some sort of sag if there was no header.
canishel,
exactly what do you mean by secondary header? If there is a 6' sliding door now why would it not be framed with a full header? If you measure the inside of the jamb of the existing door and add 1 1/2" you will get the minimum opening that there could be, and possibly more if they shimmed the door jambs. You wouldn't know if it is shimmed unless you take off the trim. I would suspect the jamb is 3/4" per side. If done correctly, a rough opening should be about 3/4" more than the outside measurement of the door.

The track should also NEVER be attached to a header in a weight bearing wall.
A secondary header should be installed with about a 1/2 inch clearance below the structural header.
If the header bows (and they all do to some extent) it can cause problems with the track.
If the wall is NOT weight bearing the header will not be loaded and you CAN omit the second header.
Decker,
You asked what I meant by a secondary header. The real answer is I don't know; I'm just parrotting what I've read. But the term was used when describing 2x4(?)as something to which the pocket door track would be attached.

BTW, this door installation is not a DIY project. I'm just trying to second-guess potential problems in construction.

Again, I apologize if I've opened a can of worms.

yourarocktome,

The addition is my version of handicap-accessible, so the spaces are larger than they would ordinarily be.
I've uploaded the plan to this response, and uploaded more pix to Photobucket, but Photobucket is giving me problems and I can't attach the link (my screen is different from those shown in the help screens).

A 30-year-old header has done all the bowing it's ever gonna do. Shim the track to the header to level and forget about it.

How about a sliding barn door? They look nice is some houses and can slide over to one side and be out of the way.

It's been 6 years and you haven't competed the project?

Thanks to all who responded.

Renovator8,
Yes, the project was finished years ago. The plan was posted to answer yourarockathome's request.
