Pat lets see if I remember right about the build.
The door is 18 foot wide by 9 foot high. (so my tractor rmops will not hit the header as it did in the basement garage)
The header is a bit wider. made of (2) 2x10 20 ft long with 1/2 inch plywood betwin them screwed and glued, clamped for a week to dry.
I am not sure if that was not the hardest part of the job lefting that up 9 foot in the air and keeping it there until we got it set.
My tractor bucket was used trying to get it up to 9ft but would not reach up that high.
I now whish I went 20 ft door but cose and span kept it to 18. it works though.
