I am looking for a 2 hour fire stopping system for a BX (armored) cable through one side of a 2 hour rated steel stud and drywall wall. The BX cable is around 3/4"
Hello Steve,
A firestop system to address this penetration is a function of many variables including (but not limited to) the type of assembly you are penetrating and the overall size of the penetration. Please take a look at the two systems that I attached. They address a large variety of cables going through common concrete (CAJ3095) and gypsum (WL3065) assemblies. The penetrant can be a single cable or a bundle of cables. If they are not exactly what you are looking for you can provide us more specific information about this condition by submitting an engineering judgement request which you can do with the instructions below:
We are proud to announce the launch of the HILTI CONSTRUCTION PLATFORM (HCP), our company’s new engineering service website. This platform will be the home for all of your Fire Protection Design needs. Instead of emailing a PDF form for a request, the platform enables you to create new Engineering Judgment (EJ) requests, submit revisions to previously completed EJs or connect with an FPE on a question. HCP also enables you to track the status of your request.
You can find more information on how to access this new platform here: http://www.hilti.com/ej (US) or http://www.hilti.ca/ej (Canada.) If you have any questions or require assistance navigating the platform, please call Customer Service for help at 1-800-879-8000 (US) or 1-800-363-4458 (Canada.)
Along with HCP, Hilti is excited to announce our new mobile app for all your firestop needs: Hilti Firestop Selector. Using the Firestop Selector app gives you easy access to the Hilti Fire Protection Design Team from the jobsite, on the road, or in the office to request a new EJ, an EJ Revision, or a Question anytime, anywhere. You can download the app using the appropriate link below.
