Dear SK,
Thank you very much for making use of our platform.
Hilti can provide a wide variety of firestop products suitable for electrical penetrations such as cable trays, cable bundles etc. The selection of the tested system and firestop product depends upon various factors such as required fire rating in hours (1/2/3/4Hrs), base material type (concrete/gypsum, wall/floor), base material thickness, opening & penetrant size etc.
Once these details are provided we will select the most optimum Hilti product tested by UL (American Std) BS/EN (British/European Std) for your application. For non-standard applications Hilti Fire Engineers can issue an Engineering Judgement.
