Hilti's CFS-CC firestop cable collar is suitable for pre-existing or new cable bundles and does not require any surface preparation.
The CFS-CC firestop cable collar provides a surface-mounted, sealant-free firestop solution for common
cable applications through floor and wall assemblies. Designed to cover maximum 4-in.-diameter openings that are 100% filled with cables, the collar is suitable for pre-existing or new cable bundles and does not require any surface preparation. Additionally, the product is constructed of a pre-formed, pre-cured material that can be re-penetrated for future cable capacity.
