We had a screen porch built. The ceiling is insulated, and one ceiling panel
has a 4" "fan channel" that runs the length.
We bought an exterior ceiling fan, and I'm confident I can run the wiring (tap
off of existing exterior light) to the fan and actually install the fan.
The only thing I am not sure of is the electric box I have to mount. How would
it mount to the ceiling? The ceiling panels are supposed to support quite a
bit of weight - I weigh 230 lbs and can walk across the top no problem.
The electric box I bought is for a ceiling fan and has three holes in it for
mounting to surface. It included lag screws but those are for a wood joist,
correct? So what hardware would I need to mount the electric box to the
ceiling, and how to go about it?
