Design and engineering choices when choosing a grease duct access door can mean the difference between life and death for building occupants and first responders.  When life safety and building performance are your number one priority, Ductmate’s ULtimate grease duct access doors are superior to the competition.

What are the ULtimate Doors?

  • UL 1978 listed

  • Meets NFPA96 standards
  • Dramatically reduces installation time
  • 11 ga. 304SS or Black Iron
