National Guard Products 160SA Silicone Dense Bulb Perimeter Weatherstrip Set – Anodized Aluminum
The National Guard Products (NGP) 160SA is a silicone dense bulb perimeter weatherstrip head-and-jamb set in an anodized aluminum finish with a black dense silicone bulb insert. Each set includes one head piece and two jamb pieces, sized and cut to order for the opening you specify. NGP engineers this seal for surface application directly to the frame stop, delivering a continuous, compression-fit perimeter seal around commercial door openings. The 160SA carries UL fire-door certifications for both standard and positive-pressure conditions, UL smoke-and-draft-control listing, and BHMA certification to ANSI/BHMA A156.22 — making it one of the most specification-complete perimeter weatherstrips available for hollow metal and wood fire-rated door assemblies. Available in five standard opening sizes: 3'0 × 7'0, 4'0 × 7'0, 6'0 × 7'0, 6'0 × 8'0, and 8'0 × 8'0. This is a made-to-order product with a lead time of approximately 10–15 business days.
High-Performance Perimeter Weatherstrip Features
- Aluminum Alloy 6063-T5 Extrusion: A precision-extruded 6063, T5 temper aluminum carrier provides a rigid, corrosion-resistant mounting surface that holds its shape across years of door cycles.
- Dense Silicone Bulb Seal: The black synthetic silicone rubber polymer compresses firmly against the door face to close perimeter gaps, delivering reliable air infiltration control and a tight seal on every close.
- Exceptional Temperature Range: Remains flexible and functional from –81 °F to 300 °F, making it suitable for cold-storage entrances, industrial environments, and locations subject to extreme heat.
- Flame- and Moisture-Resistant: The silicone formulation resists both ignition and moisture absorption, supporting performance in demanding interior and protected exterior applications.
- Ozone, UV, and Aging Resistance: Silicone's inherent molecular stability means the bulb resists degradation from ozone exposure, ultraviolet light, and long-term aging — reducing maintenance replacement cycles.
- FM200 and Halon Compatible: NGP specifically recommends the 160SA for rooms and corridors protected by FM200 or Halon gaseous fire-suppression systems, where seal integrity under suppression discharge is critical.
- UL Fire-Door Certified (Standard Pressure): Certified by UL to CAN/ULC-S104 and ANSI/UL 10B; 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.
- UL Positive-Pressure Fire-Door Certified: Certified by UL to ANSI/UL 10C; complies with IBC, NFPA 80, and NFPA 252 for hollow metal fire doors rated up to 3 hours and wood fire doors up to 90 minutes under positive-pressure conditions.
- UL Smoke & Draft Control – Category 'H': Certified by UL to ANSI/UL 10C and ANSI/UL 1784 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 up to 90 minutes.
- BHMA Certified to ANSI/BHMA A156.22: Independently certified for door gasketing and edge sealing performance — including heat and cold tests — and listed in the BHMA Certified Products Directory.
- Slotted Screw Holes for Field Adjustment: Pre-slotted mounting holes allow precise in-field adjustment of the seal's compression point without drilling new holes.
- Stainless Steel Fasteners Furnished: Each set ships with #6 × 3/4″ stainless steel sheet metal screws — corrosion-resistant hardware matched to the aluminum carrier for long-term integrity.
- Head-and-Jamb Set, Five Opening Sizes: Sold as a complete three-piece set (one head, two jambs) cut to the opening size you select — 3'0 × 7'0, 4'0 × 7'0, 6'0 × 7'0, 6'0 × 8'0, or 8'0 × 8'0 — eliminating job-site cutting of the aluminum extrusion.

Pro-Tip for Perimeter Sealing
The NGP 160SA is designed for surface application directly to the frame stop — the raised rabbet on the inside face of the door frame against which the door closes. The slotted screw holes in the aluminum carrier allow you to shift the strip slightly toward or away from the door face before final tightening, so you can dial in the right compression on the dense silicone bulb without over-compressing or under-sealing. All required #6 × 3/4″ stainless steel sheet metal screws are furnished with the set, so no separate fastener sourcing is needed on the job site. For fire-rated openings, always confirm that the complete assembly — door, frame, closer, and gasketing — is covered under the door manufacturer's UL listing before installation.
