    Where can I find metal fireblocking plates for around plumbing?
    Does anyone know where to find the sheet metal or tin plates with holes in them that are used for fireblocking around 1 1/2", 2" PVC pipes, and copper water lines?
    I've seen them in 2 different houses and I was talking to one of the building inspectors and he was telling me that he wants to see no more than 1/8" gap around pipes going through the top plate in a finished basement. I couldn't find them at Lowe's.
    Or does anyone have any other ideas for fireblocking besides the caulking?

    Interesting - this is a not a requirement where we live
    I could not find metal ones - if I was doing this, I think metal would be a last resort. "Great stuff Pro" seems to be approved and there are a number of caulks specifically for this purpose.

    I also read that some jurisdictions allow fibreglass batts filling the stud wall for 16" above where the hole is.

    Best bet is to ask your inspector again if he has a preference.
