What concerns should I have about hanging from old wood?
Like very old wood, almost petrified?
I'm doing an NFPA 13R job for an old historic building that has been moved. I don't know how old, but it uses full dimension wood. The 2x's look like they measure 2-inches thick.
I'm wondering what hanging to this old dry wood is going to be like?
Do they need to predrill? Are screws better?
Any ideas appreciated!
