Five-sided drywall box listed membrane penetrations

[BN4537]

Does anyone know if there is a system similar to the one I am attaching for wood construction? I didn't even know this one was available, a contractor sent it to me.

I like to keep stuff like this in my back pocket to get people out of tight spots. Some would say that it's not my problem, but if it gets a project out of my hair faster it is the smart thing to be able to do...

Interesting...Also recessed heaters in the exit enclosures....But if there is not an actual Listing, it's an EJ and needs to have all of that documentation....
