There are 40 3/4" conduits already installed thru a firewall, they are tight to the concrete deck and they need to have a 1/2" barrier between the concrete and the top of the conduit. Is there a sleeve or assembly we can get that will give us this dimension and also achieve the 2 hr firestop rating required. Thanks.
Hey Dan - 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.
