Hello,

I'm planning to do a 25' run of 2" cast iron pipe between floor joists
and am thinking about how to properly support it. There are pipe
hangers that I could use to support it from above, so I would have to
attach these to the subfloor. I was wondering if instead there is a
type of support I could use that would attach to the joists on either
side. Something like the expandable bar support on a fan-rated
ceiling electrical box. Any suggestions or pointers?

Thanks, Wayne
