  • SECURITY GREASE DUCT

    Integrated centering sleeve stabilizes the tubes during assembly and covers joint grooves that might otherwise be exposed and trap grease contaminants. Also provides a channel for high temp sealant to accurately insure system water tightness. Extra large spacing between outer wall sections allows for quick and easy installation of the securing band.

    Fire-rated (CIX3Z) significantly reducing installation footprint and frees up space for other use. No need to build an expensive fire-rated chase or apply two layers of fire wrap typically required for welded steel grease duct designs.

     
    Available in 5″- 36″; 3″ wall insulation and single wall. Secure Stack Pro is now UL 1978 listed for applications where 1” air insulated, 1”, 2”, or 4” AES Wool Insulated grease duct is required. Please see the Secure Stack Pro product pages for more details.

     
    UL1978, UL2221 (2 HR)
    IMC, UMC and NFPA96 Code Compliance

     
    Blanket insulation is already installed in the portion that lines up with the outside casing. We provide an insulation band to be field installed behind the outside band.

    Goes together with the inner flange and inner locking band (with centering extension). The outer locking band is on the outside for more support, making it a stronger system.
