Firestop solution from Hilti
Hilti’s CFS CID 8” and 10” firestop cast-in devices are for 8” and 10” pipes for water drainage and large pipe applications. These one-step firestop solutions work with 8” PVC, metal pipes with insulation, as well as 8” and 10” metal pipes — no additional sealing is required. They are available in 6”, 8”, 10”, 12” and 14” heights. The cast-in devices are ready to use right out of the package and the installation process is simple, requiring only one laborer, which helps lessen the chance of project delays caused by failed inspections. They work with PVC, metal and metal with insulation pipes, and they do not have an expiration date (no shelf life).
