Hilti has launched the CFS-CID firestop cast-in device for new construction in-situ concrete slabs, featuring a thinner, more powerful integrated firestop collar to allow greater tolerances around pipes and a smaller footprint.

The new ETA-approved firestop device is available in four sizes covering a range of pipe diameters from 40-160mm, and has a standard height of 250mm. Modular 150mm extension tubes can be securely attached to increase the height of the cast-in device for use in thicker slabs. These can be stacked and cut to achieve any required elevation.

An external thread gives a secure connection to the lid and the ability to add CFS-CID accessories, including a manifold adapter to create a 280x280mm square opening which creates a 75mm void ideal for pipe junctions, manifold or elbows.
