National Guard Products 130SSS Stainless Steel Silicone Perimeter Weatherstrip Head and Jamb Set
National Guard Products (NGP) model 130SSS is a stainless steel silicone perimeter weatherstrip head-and-jamb set finished in a Brushed #4 Stainless Steel (US32D / 630) housing with a black closed-cell silicone insert. Each set is made to order and ships with one head piece and two jamb pieces sized to fit your specific opening — available in five standard door sizes: 3'0 x 7'0, 4'0 x 7'0, 6'0 x 7'0, 6'0 x 8'0, and 8'0 x 8'0. The 130SSS is UL-certified for fire door applications up to 3 hours on hollow metal doors and up to 90 minutes on wood fire doors, and it carries positive pressure, smoke and draft control, and ANSI/BHMA A156.22 certifications — making it one of the most specification-ready perimeter seals available for high-demand commercial and institutional openings, including those protected by FM200 or Halon fire suppression systems.
130SSS Silicone Perimeter Seal — Key Features
- Type 304 Stainless Steel Housing: The carrier is fabricated from Type 304 stainless steel with a Brushed #4 finish (US32D / 630), providing long-term corrosion resistance in demanding environments.
- Closed-Cell Silicone Insert: The black silicone synthetic rubber polymer seal delivers exceptional flexibility and memory, ensuring a consistently tight perimeter closure across repeated door cycles.
- Extreme Temperature Performance: Rated from -81°F to 300°F, the silicone insert remains flexible at both extreme cold and high heat — critical for fire-rated openings and exterior applications subject to wide thermal swings.
- Flame and Moisture Resistant: The closed-cell silicone construction resists flame penetration and moisture infiltration, supporting the seal's performance in fire-rated and weather-exposed assemblies.
- Ozone, UV, and Aging Resistance: The silicone polymer resists degradation from ozone, ultraviolet exposure, and long-term aging, reducing maintenance and replacement frequency.
- FM200 and Halon Compatible: Specifically recommended for areas protected by FM200 or Halon gaseous fire suppression systems, where seal integrity under suppression discharge conditions is essential.
- UL-Certified Fire Door Compliance: Certified by UL to CAN/ULC-S104 and ANSI/UL10B (standard pressure) and ANSI/UL10C (positive pressure); complies with NFPA 80 and NFPA 252 for hollow metal fire doors rated up to 3 hours and wood fire doors rated up to 90 minutes.
- Positive Pressure Rated: UL-certified to ANSI/UL10C and compliant with IBC, NFPA 80, and NFPA 252 for positive pressure hollow metal fire door assemblies rated up to 3 hours.
- Smoke and Draft Control Gasketing: Certified by UL to ANSI/UL10C and ANSI/UL1784 Category 'H'; complies with IBC and NFPA 105 for use on 'S'-labeled positive pressure hollow metal fire doors up to 3 hours and wood fire doors up to 90 minutes.
- ANSI/BHMA A156.22 Certified: Performance-tested and certified to the American National Standard for Door Gasketing and Edge Sealing Systems, listed in the BHMA Certified Products Directory — including heat and cold performance tests.
- Air Infiltration Control: Recommended for achieving minimum air leakage and a tight perimeter seal around commercial door openings.
- Slotted Screw Holes for Field Adjustment: Screw holes are slotted to allow precise positioning during installation, accommodating minor frame variations without remounting.
- Stainless Steel Fasteners Furnished: Each set includes #6 x 3/4" stainless steel sheet metal screws (SMS), maintaining material consistency with the stainless steel housing and eliminating rust-staining risk.
- Five Opening Sizes Available: Offered as a made-to-order head-and-jamb set in 3'0 x 7'0, 4'0 x 7'0, 6'0 x 7'0, 6'0 x 8'0, and 8'0 x 8'0 to suit single and double door openings of various heights.

Pro Tips for Specifiers and Installers
The 130SSS is screw-applied directly to the frame stop, and the slotted screw holes allow you to fine-tune the position of the seal before final fastening — a critical step for achieving consistent compression across the full height and width of the opening. Because both the housing and the furnished fasteners are stainless steel, the 130SSS is particularly well suited for high-humidity environments, coastal installations, and food processing or pharmaceutical facilities where corrosion resistance is a priority specification requirement. When specifying for a fire-rated opening, confirm that the door and frame assembly carries the appropriate 'S' label if smoke and draft control compliance under NFPA 105 is required by the authority having jurisdiction (AHJ). Because this item is made to order, verify your rough opening size before placing your order to avoid delays.
