Garage Door Opener Help

Yes, it works very well, and on the first try too! Usually, electrical/electronic things are easy. It's all the other stuff that's a challenge.

So, those beams are just to keep the walls from bowing out? I though it worked to keep the walls from going either way. If that's the case, a steel cable would have been easier, although would be dangerous if it ever broke and someone was nearby.
