Fire-rated Wiring System

Thomas & Betts’ Steel City fire-rated poke-through system provides functional floor-level power and communications in commercial buildings for wiring configurations. It is available in three- and four-inch core drill sizes and offers an organized system for telephone jacks, AC adaptors and other outlet needs. It enables the user to modify and upgrade the system without exposure to power compartments.


The system is available in solid brass and aluminum finishes as well as four powder-coat finishes of black, grey, beige and brown. It can be used for power and communications wiring in a single access point to feed modular furniture, and for flush power and communications.
