In which application would you likely see Colar used?

Colar is specifically designed to be used in firestop material installations. The primary purpose of Colar is to create a barrier that prevents the spread of fire, smoke, and hot gases through openings in fire-rated walls, floors, or ceilings. In such installations, Colar acts as a key component to help maintain the integrity of fire-resistive assemblies, ensuring that firestop systems perform effectively under fire conditions.

While fastening components, cable management, and marking tools each have distinct roles in their respective applications, they do not possess the specialized functionality required for maintaining fire resistance and compartmentalization, which is crucial in firestop systems. Hence, Colar's application in firestop material installations is critical for achieving compliance with fire safety standards and protecting structural integrity.
