National Guard Products 107SA Adjustable Silicone Perimeter Weatherstrip – Anodized Aluminum | Head-and-Jamb Set
National Guard Products (NGP) Model 107SA is a UL-certified adjustable silicone perimeter weatherstrip finished in Anodized Aluminum and sold as a complete head-and-jamb set (one head piece plus two jamb pieces) sized to fit your opening. Five standard opening sizes are available — 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 — making the 107SA an engineered perimeter seal solution for a wide range of single and pair openings in commercial, institutional, and high-security applications. The extruded Aluminum Alloy 6063-T5 retainer houses a black silicone seal that delivers outstanding flexibility, memory, and environmental resistance across a temperature range of -81°F to 300°F, while meeting rigorous fire, smoke, and positive-pressure standards for both hollow metal and wood fire-rated doors.
107SA Adjustable Perimeter Seal – Key Features
- UL Fire-Door Certification (Standard & Positive Pressure): Certified by UL to ANSI/UL10B and CAN/ULC-S104 (standard fire) and to ANSI/UL10C (positive pressure), complying 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.
- Smoke & Draft Control – UL 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 rated up to 3 hours and wood fire doors rated up to 90 minutes.
- Adjustable Retention System: Adjustment screws spaced on 10-inch centers allow fine-tuning of seal compression across a 1/4-inch adjustment range without re-positioning or relocating the mounting holes — critical for field-fitting on out-of-square frames.
- High-Performance Silicone Seal: The synthetic rubber polymer (silicone) insert maintains excellent flexibility and memory at extreme temperatures (-81°F to 300°F), resisting ozone, UV radiation, moisture, and long-term aging.
- Flame-Resistant & Moisture-Resistant Construction: Both the Aluminum Alloy 6063-T5 retainer and the silicone seal are engineered for flame resistance and moisture resistance, supporting use in demanding environmental conditions.
- Compatible with FM200 & Halon Fire Suppression Systems: Specifically recommended for areas equipped with FM200 or Halon gaseous fire suppression systems, where seal integrity during suppression events is essential.
- Air Infiltration Control: Recommended by NGP as a minimum air-leakage solution, providing a tight perimeter seal that reduces energy loss and pressure differentials around the door.
- Furnished Stainless Steel Fasteners: Each set ships with #6 x 3/4" or #6 x 1-1/2" stainless steel sheet metal screws (SMS) — no separate hardware purchase required.
- Anodized Aluminum Finish: The Anodized Aluminum retainer finish provides corrosion resistance and a clean, professional appearance compatible with standard commercial door and frame hardware.
- Head-and-Jamb Set: Supplied as a matched set of one head piece and two jamb pieces cut to the selected opening size, simplifying ordering and ensuring consistent seal performance on all three sides of the opening.

Pro Installation Tip
Because adjustment screws are located on 10-inch centers, installers can fine-tune seal compression at each fastener point across the 1/4-inch adjustment range without drilling new mounting holes — a significant advantage when fitting the 107SA to frames with minor warping or alignment variation. The furnished stainless steel sheet metal screws (choose #6 x 3/4" for thinner substrates or #6 x 1-1/2" for deeper frames) are included with each set, so no separate fastener sourcing is needed on the jobsite.
