Garage door opening?

From my past installs and framing.  I would frame it out to the width of the door, then when you install the trim/weather-strip, good to go.  As for the height of it, do the same. So rough frame at 8x7 trim, 3/4" ???,  weather striping approx. 1/4" to 3/8" you should be good.   Just my opinion, if others have more input, chime in!!!

this is a little confusing to start, but in the END the opening is 8 x 7 as I mentioned.

What are you "trimming out" the opening with?? The rough opening is based upon the "finished" trim, don't figure in the weather strip. Normally a O/H door is rough framed 3" wider and an 1 1/2" taller to allow for 2x? side jambs. If 3/4" trim is used, adjust as needed. Too small of an opening(within reason) is WAY better than too big.

I need to frame out an opening for a garage door. I'll probably end up buying the 8'x7' roll up style door at Lowe's. All it says on the box is 8x7. Does the opening need to be a little larger? I just wonder if I need room for tracks and other hardware? If anyone has ever installed one I would appreciate any info, thanks.

Then on the inside lay a 2x6 flat against the crippled and stud running from floor to ceiling on each end then run one horizontal between the two ends flush with the bottom of the header. You’re creating an “H” frame. Then find center and run a short 2x12 or (2) 2x6 side by side from the top of the horizontal 2x6 to the ceiling. This is to mount the spring hanger in the center. This will move your door in 1 1/2” and gives something to drywall up against should you chose. It also gives a full 51/2” to mount the door tracks to.   You guys waste WAY too many $$ with your 2x6's LOL!!

Both overhead door companies we use require the H frame and the Drywaller love us.
We have a 2.5 year waiting list right now so I’d say our customers must be happy.

If I understand this correctly from what FREEDGUY wrote and Steve(ill)'s link, you should frame it out wide enough to allow for your casing material (in most cases 2x6). The actual opening should end up being 8ft wide x 7ft high. The lumber I'm using is sawmill lumber, so my 2x6s are a full 2" thick (not 1 1/2 x 5 1/2). I can allow for this extra amount as long as I end up with a 8x7 opening. I should probably just go ahead and buy the door and see before I build the wall.

It's funny, I was asking them at Lowe's how big the opening needed to be for there doors. No one knew. They told me they had people that could install it for me. I told them they couldn't install it without anything to install it to. I would still need the right size opening no matter who installed it.

If you rough in the opening to 8 x 7, then you can nail a 3/4 pine board to it to overlap the door... the FINAL opening will be 1-1/5 inch smaller than 8 ft.........

I can't understand smaller being better. The door has to go inside the opening, if it's too small it can't. If it was to wide you could shim it with some thin plywood or something. It might not look good, but I guess a man could make it work. Maybe I don't know how these doors install. I'm just trying to avoid a mistake, thanks for your help.

I installed a 4 x 7 rollup door purchased from Menards (Ideal model 200) for my 12 x 14 wood shop. I made the finished opening 4 x 7 per installation instructions. Ensure you use double studs 3" on each side of the opening for attaching the side rails for the door. You also need at least 15 1/2 inches of headroom above the 7' opening height. I installed drywall and wrapped the opening with tin prior to installing the door. If you go on the internet and lookup the model number listed you can find the installation instructions. Really like my door to the wood shop. Regards, Tom

For this kind of work, it is best for you to contact the service. Just a knowledgeable person can help you much better than advice from the Internet. If there are serious problems with any equipment, then you need to contact the repair service. I had a similar situation to yours, only because I decided to fix everything myself, I finally broke the door. I had an electronic front door that I opened with a remote control. After three years, it stopped responding to the remote control and I tried to fix it and I finally broke down the door. After I found a detailed description of the doors made of solid pine on the Internet, I decided to buy it.
