  • Flush cover design – Base sidewall is even with cover for superior aesthetics and greater wiring capacity when compared to non-flush cover wiring duct
  • Non-slip cover liner – Halogen-free liner ensures that the cover does not slide during shipment, vibration, and when in a vertical orientation, eliminating rework and repositioning
  • Base and finger score lines – Score lines allow for easy breakouts, saving installation time, when score lines compared to other halogen-free duct
