I am installing a ceiling fan in a room over which I have attic access. There is an existing light fixture where I will be putting the fan, but the box it is mounted to is not rated for ceiling fans.
Rather than using the spreader-bar type kit often shown in tutorials, I was planning to simply use a length of 2x8 to span the ceiling joists where the new electrical box will go. I would really like to avoid having a ceiling fan fall on my head (or anyone else’s for that matter) and want to know the best way to attach the 2x8. I would like to make sure that however I end up attaching it, that it is safe and meets code .
Hardware and materials:
- 4” Ceiling Fan rated box
- Ceiling fan (20 lbs)
- GRK R4 #9 x 3-1/8” screws
My question is, what is the correct way to attach the new 2x8 to the ceiling joists? Should I:
- Toenail the screws in from a 45 degree angle (see “A” on diagram)
- End nail (screw?) in from the ends at a 90 degree angle (see “B” on diagram)
Either way, I was planning to use four screws on either end, for a total of eight screws between the joist and the new 2x8.
