3M - CP 25WB+ Fire Caulk application specific to MC cable.
(OP)
Hello all, I am trying to find some information regarding the application of 3M-CP 25WB+ Fire Caulk to MC cable penetrating a 2hr rated block firewall. I have the literature in respect to flexible metal conduit, unfortunatly I've not found anything specifically related to MC cable. Any information will be appreciated.

I have yet to see a through penetration fire stop assembly for cables that has not required the installation of conduit.
