applications for CFS-CID MD cast-in devices


  • Opening creation in corrugated metal deck slabs to run pipes or conduits 
  • Designed to work in composite W3 and W2 floor decks for a wide number of manufacturers 
  • Sealing combustible and non-combustible penetrations 
  • For slab thicknesses from 2.5” up to 6” from top of the deck 
  • Concrete floor assemblies rated up to 3 hours 


  • Peace of mind — cast-in devices help remove scope for errors compared to traditional methods 
  • Creates an opening with the firestop already included — no coming back for firestopping required 
  • Integrated moisture and smoke seal — no additional backfilling required 
  • Steel deck reinforcement or additional shoring may not be needed to support the steel deck as a form during the construction phase 
  • Deck is cut after concrete is cured and unlikely interfere with reinforcement 
  • No need of torches, plasma cutters or core rigs to perform the penetrations
