Protect electrical boxes and service penetrations with a pliable 3M fire barrier putty pad that moulds by hand without mixing or tools. The self-adhering, intumescent material provides a draft and cold smoke seal and can be joined with additional pads for larger firestop applications. Its re-enterable, non-drying construction makes future access easier on commercial construction projects.
