Hi,

I am new to this forum and this is my first question. I am about to install a ceiling fan in my dining room and I discovered that I am going to have to replace the current ceiling box as it is plastic and the holes are stripped. I took out the box, it was mounted to a metal, extendable brace that is NAILED to the studs on either side. My question is: Does the brace has to be screwed in or is it ok to be just nailed. I pulled down on it, and it didn't go anywhere and there is no play in it, but I'm wondering if the vibration from the fan could loosen it over time.

Thanks for any help,

-Colin
