Did you cut around the door backhangs? The left door doesn't even look like it has an angle piece to keep it from rocking, it it doesn't I would get one on there. I would probably make the one on the right door a little longer for more strength. You can just mount the angle over the top of the metal no problem. I wouldn't tighten it too much though to keep it from bending the metal all up.
On another note I would suggest against the Wayne Dalton operator nothing but problems.
Wow...good eye. I have been in and out of that building hundreds of times and never noticed that. It looks like the builder forgot to finish that one, since all the others are done. I have added a piece and it is much more stable. Thanks for picking that up.
Are you suggesting that the angle bracket for the opener can be mounted on the 1"drop that is caused by the shape of the ceiling panel? I had the same thought. Since there is a 1" air space between the metal and the truss, I thought about driving lag screws through the angle bracket into the truss, but only snugging them to the poit where they do not deform the metal.
Or, do you think I can just put a 2X4 above the ceiling and screw directly into that. The metal is 29 gauge, and is pretty sturdy (I have stepped on it before without it deforming)?
Either way, I could not get anything done due to not having a long enough opener (my door is 8' instead of 7'). I also can not find an upper door support for my door with an 18" panel on top rather than a 22" panel. Any suggestions?
