Hello,
Thank you for reaching out to the Hilti Fire Protection Design Team to assist you with your firestop engineering needs.
We do not have a listed system for a membrane penetration though a gypsum shaft wall assembly; however, we can address your application through an Engineering Judgment, which will be a custom detail showing your exact application with the firestop components required to maintain the stated ratings.
