I need a UL for 3" PVC through a gypsum Board 2x4 wall
Hello Adam,
I've attached a couple of systems that may meet your needs. If you'd like to see more options available, you can check out our Firestop Selector on the Hilti Construction Platform. If none of those solutions will work for you, you can submit for an Engineering Judgement below. I've attached addition information for the Firestop Selector and Engineering Judgements below. You can also call us at 1 (800) 879-8000 and we can help you over the phone. If these systems do not work for you, you are able to submit an engineering judgement (EJ) as well. Please see below how to log into our platform.
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.
Hilti Firestop Selector App – Google Play Store

If you have any questions, please reach out to our customer service team at 1-800-879-8000 (US) or 1-800-363-4458 (Canada) for assistance.
Best regards,
Fire Protection Design Team
