I would like to know what Hilti thinks of this installation of its products and whether Hilti would think that these penetrations are actually going to stop the spread of smoke and fire. There is no annular space no rigid support on both sides and I think they just stuffed red sealant in there. I have lots more photos. Hilti products were submitted for this project and I wonder if Hilti should go take a look at what was installed. Also are your products warranted if installed by people not trained to install them?
