Dave,
I checked with the OHD company and was told even with the double track i still need 15" of clearance to accommodate the door and future opener. Plus the door would be an odd size, which of course means more money.
Opener? You plan on living large. :laughing: My tractor cave door is 9' x 16', no opener. It isn't any sort of struggle to open and close in case you wonder. Openers are worth their weight in gold on a house garage for sure. I guess it depends on how much going and coming you will be doing whether an opener for the barn/shop is needed. They are nice to have.
The opener on our house garage door is 8" tall, so to give it some ceiling clearance, it would need 10" from the ceiling down, minimum.
I measured my tractor cave door to see how that compares with the requested 15".
The floor to ceiling height is 116-1/2".
From the floor to the top of door when closed is 109-1/2". 9' door plus ~1-1/2" for the seal at the bottom of the door.
The double track drops 6" below the ceiling. That is outside the door width anyways, it doesn't limit the clearance.
The bracket that holds the shaft, springs and tracks is 10" tall, but again that is beside the door opening, not in it.
The top of that bracket is ~2" above the ceiling surface, that is what I boxed in up in the truss space, and ended the ceiling sheathing on the next to last truss.
The door when open gives 102" of clearance, I could get 3" more if the springs were adjusted to pull the door all the way back, an opener would be even easier to adjust.
So, I have a 9' tall door installed in a 9'-8 1/2" ceiling height. I did fudge a couple inches with the boxed in spring shaft above the ceiling, and my door extends a couple inches more than necessary above the opening when closed; I could never get the full 108" of open door clearance--about 105" maximum.
I think if you wanted, you could have an 11' tall door with an opener--given your 12' high walls--and have most of the door height usable.
If that was of interest, you could shop around on door manufacturers. For example Overhead Door Co. will apparently make any height door you want up to the limit for the given door model. I don't know if they charge more for an oddball size, and you may end up with one odd height panel that doesn't match the others.
Just info, useful or not.
