National Guard Products 106SA Adjustable Silicone Perimeter Weatherstrip Head-and-Jamb Set – Anodized Aluminum
National Guard Products (NGP) model 106SA Adjustable Silicone Perimeter Weatherstrip delivers a high-performance, fire-rated perimeter seal for commercial door openings that demand lasting flexibility, smoke and draft control, and positive-pressure fire-door compliance. Supplied as a complete head-and-jamb set — one head piece and two jamb pieces — this listing is available in five opening 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 extruded Anodized Aluminum retainer houses a black silicone bulb seal rated from -81°F to 300°F, making the 106SA an ideal weatherstrip for hollow metal and wood fire-rated doors in hospitals, schools, government buildings, data centers, and any facility using FM200 or Halon fire-suppression systems.
106SA Silicone Perimeter Weatherstrip – Key Features
- Aluminum Alloy Construction: Retainer is extruded from Aluminum Alloy 6063, T5 Temper for rigidity, corrosion resistance, and a clean anodized finish that blends with commercial door frames.
- Black Silicone Seal: Synthetic rubber polymer silicone bulb delivers excellent flexibility and memory, maintaining a consistent perimeter seal across the full temperature operating range of -81°F to 300°F.
- Adjustable Without Re-Positioning: Adjustment screws placed on 10-inch centers allow fine-tuning of the seal compression — up to 1/4 inch of adjustment — without moving the mounting screws or stripping the door frame.
- UL Certified – Standard and Positive Pressure Fire Ratings: Certified by UL to ANSI/UL10B and CAN/ULC-S104 (standard pressure), and to ANSI/UL10C (positive pressure); complies with NFPA 80, NFPA 252, and IBC for hollow metal fire doors rated up to 3 hours and wood fire doors rated up to 90 minutes.
- Smoke & Draft Control – Category H: 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.
- BHMA Certified to ANSI/BHMA A156.22: Independently certified and listed in the BHMA Certified Products Directory for heat, cold, and energy performance — the recognized industry benchmark for commercial door gasketing systems.
- Flame and Moisture Resistant: Silicone compound is flame-resistant and moisture-resistant, suitable for exterior perimeter sealing and interior fire-separation assemblies alike.
- Ozone, UV, and Aging Resistance: Silicone formulation provides excellent resistance to ozone and ultraviolet degradation, ensuring long service life in high-cycle commercial openings.
- FM200 / Halon Compatible: Specifically recommended for clean-agent fire-suppression environments where gasket material integrity after agent discharge is critical.
- Stainless Steel Fasteners Furnished: Each set includes #6 x 3/4" or #6 x 1-1/2" stainless steel sheet-metal screws to resist corrosion in demanding installations.
- Made to Order: Custom-cut to the selected opening size with an estimated lead time of 10–15 business days.

Pro Tip: Because adjustment screws are spaced on 10-inch centers, installers can fine-tune seal compression across the entire head and jamb length without relocating mounting holes — a significant advantage on steel frames where re-drilling is not practical. Stainless steel fasteners in both 3/4" and 1-1/2" lengths are furnished to accommodate varying door frame wall thicknesses commonly encountered on hollow metal frames.
