Joseph,
I'm not sure if you are looking for help identifying a UL listing for the design of the wall itself or if you're looking for a firestop solution through this wall. I will approach this by answering both situations:
- Hilti does not design assemblies, so while I cannot definitively point you to a design, the wall appears to be specified as U419 on the detail you attached. When I look up a U419 wall, it does appear that the minimum width for the studs is specified but no maximum, so it's possible that you could use the U419 design for this assembly if the other parameters are met. I would recommend consulting a third party on this since this would not be in Hilti's direct scope to help identify the design of the wall assembly.
- If you are looking for firestop solutions for 3-hr. walls, then we have several. I attached a head-of-wall and bottom-of-wall system as an example, but we have multiple other solutions in our library of systems. I would recommend logging onto our website and searching through the Hilti Firestop Selector to take a peek through our various systems. 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, including the Hilti Firestop Selector. 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.)
Thank you,
