The EZ Path® Series 33 Fire-Rated Pathway provides a maintenance-free firestop solution for routing moderate cable volumes through fire-rated walls and floors. Engineered for reliability and compliance, the Series 33 features integrated intumescent pads that automatically adjust to changing cable fills—eliminating the need for manual intervention. When exposed to elevated temperature or direct flame, these intumescent pads rapidly expand, forming a dense, insulating char that effectively blocks smoke, hot gases, and flame. This ensures consistent firestopping performance while supporting safe and efficient cable management in commercial, industrial, and technology-rich environments.
