Do you have any idea what size your door will be. It was after dark by the time I got done with the 350 ton crane and I didn't get a chance to take any pictures. I can whip you up some drawings if you can get me the size. The opening size that is. Mine is powered with a commercial garage door opener. The type that has a brake on the outside. One section has to be taller than the other so that it won't go past center and fold up on you. I have 2 - 1/4" cables that pull it up. One is more than sufficient the second is saftey factor.
The frame is made from 2x4x1/8 tubing for the perimeter and 12ga. tube for the internal braces. With formed 1 1/2" angle for purlins I guess you would call them. The frame doesn't need to be real heavy. With the sheetmetal screwed to it, it aquires a lot of strenght. I also glued 1" foam insulation with the foil on both sides to the inside for insulation.
I am working out of town for the week. 3 hrs. from home. I won't be able to get you any pictures until the weekend.
Hope I can be of some help.

go to www.bifold.com
there some nice stuff on there,you can see how the opener works too.
they are using flat straps to lift the door and thats what i'm going to use.
to stop the door from opening to far you can weld a stop to the door jam or make the top door smaller,
Randy

Weldor, That is a clever opener. Bet it works well.

is that boomer just a lock or does the door not completely close in the down position?
some bi-fold doors don't seem to close all the way at the part line, where the hinge is.
i'm wondering how to overcome that little glitch!
Randy

ohh,nice door!
