Hello,
Thank you for reaching out to the Hilti Fire Protection Design Team to assist you with your firestop engineering needs. Please see attached for Hilti ul/cul classified system W-L-7319.
If this system will not meet your exact application needs, 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.
