Hello,

Thank you for reaching out to the Hilti Fire Protection Design Team to assist you with your firestop engineering needs.

We have several systems that can address cast iron through concrete floors/ceilings. I have attached a few of our most common systems, but we have much more than these. You can view additional systems on the Firestop Selector through either the Hilti Construction Platform or the Hilti Firestop Selector app (information below).

Hilti is proud to announce the launch of our engineering website, the HILTI CONSTRUCTION PLATFORM (HCP). This platform will be the home for all of your Fire Protection Engineering needs. You can find more information on how to access this new platform here: https://www.hilti.com/ej (US) or https://www.hilti.ca/ej (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 ask a Question anytime, anywhere. You can download the app using the Google Play Store or Apple App 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 or use the following link to access the How-To Videos for HCP on YouTube: Hilti Fire Protection Software How-To Videos Playlist

Good morning. Thank you

I don't have access to the top side of the hollow core floor. We are in a restoration project to pre existing pipes and concrete slab. No ability to sleeve the penetrants. I believe the closest assembly I've found is F-B-1035. I've requested an EJ to include double layer 5/8's GWB to close the annular gap and fill with FS One max
