3Hr Rated

Need to have sleeves and firestopping through this wall but they are asking 3 hr assembly.
Anyone aware of any firestopping that would provide 3 hr rating? Thanks

Forget about the firestop what wiring method are you using that has a 3 hour fire rating?

But that only works for drywall on steel studs. You have to know what the wall construction will be.

Here are some examples - its a USG Fire Resistant Assemblies PDF:
