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.

It sounds as if 3M has not evaluated this assembly for a cable run through a wall. I do know that 3M has its own fire test furnance and they may be able to run a test for you and issue a report for this assembly using MC cable.
I have yet to see a through penetration fire stop assembly for cables that has not required the installation of conduit.
