Ductmate’s ULtimate grease duct access doors provide easy access to high-temperature air ducts and grease duct systems and were designed for applications requiring UL 1978 listing. We offer the ULtimate Door (sandwich-style), ULtimate Door II (weld-on), and the ULtimate Door Round (sandwich-style for round duct). Unlike shop-fabricated and inferior, light gauge grease duct door substitutes, the high-performance line of ULtimate Grease Duct Access Doors from Ductmate are designed to meet the challenges. They are the most extensively engineered, tested, and ruggedly constructed doors available in the industry.
