  • Provides maximum resistance when there is fire or smoke present, whether empty or completely filled
  • Click for More Features

The E-Z Path® fire rated pathways are raceway devices that are designed to allow cables to go through fire-rated walls without the need for additional firestopping materials. These units are equipped with a built-in fire sealing system which adjusts to the number of cables that are being installed. Once installed in a fire barrier, you can easily and quickly add, remove, or reinstall fire stopping materials.

  • Whether new construction or retrofit, you are assured protection from fire and smoke with every cable installation
  • Superior resistance to fire and smoke seepage, unlike the standard sleeve and putty systems
  • Created so that it rapidly expands once exposed to fire or high heat
  • Intumescent material reacts to the heat and flames by rapidly sealing the pathway and stopping the flow of fire and smoke
  • UL Classified and FM approved in accordance with ASTM E-814 (UL 1479)
  • 4 hour rated floor and wall constructions
  • Remains code compliant at all times, whether it is empty or full
  • Tested and approved cable capacities range from 0 to 100% visual fill
