Open end conduit penetrating 2hr barrier. Extends about 12" off the wall. Couldn't find a specific UL System for it. We found one where the conduit is allowed to be flushed or max 2" off the wall. We have some of them through gypsum board and some through cement block. Looking for solution , we can cut the sleeves down if needed and if no other option available. Conduits are blank , example attached.
Thanks in advance!
