National Guard Products 160UA Polyurethane Perimeter Weatherstrip Head-and-Jamb Set – Anodized Aluminum
National Guard Products (NGP) 160UA is a polyurethane perimeter weatherstrip head-and-jamb set in an Anodized Aluminum finish with a black polyurethane insert, engineered to deliver a tight, code-compliant seal around commercial and institutional door openings. Each set includes one head piece and two jamb pieces, screw-applied directly to the frame stop, and is available in five standard 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 160UA is UL-certified for use on hollow metal fire doors rated up to 3 hours and wood fire doors rated up to 90 minutes, covering both standard and positive-pressure fire door applications. With its Thermo-Plastic Vulcanizate (TPV) bulb seal housed in an Aluminum Alloy 6063-T5 carrier, the 160UA is a trusted specification-grade solution for architects, contractors, and facility managers seeking durable, flame-resistant perimeter protection.
High-Performance Perimeter Weatherstrip Features
- UL-Certified Fire Door Performance: Certified by UL to CAN/ULC-S104 and ANSI/UL10B, and to ANSI/UL10C for positive-pressure applications — 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 Certified: Meets ANSI/UL10C and IBC requirements, making the 160UA suitable for stairwell, corridor, and other positive-pressure fire door installations.
- Aluminum Alloy 6063-T5 Carrier: Extruded from high-quality 6063-T5 aluminum alloy for a rigid, corrosion-resistant frame that holds its profile over the life of the door.
- Thermo-Plastic Vulcanizate (TPV) Seal: The black TPV polyurethane bulb offers very good abrasion resistance, tensile strength, memory, and UV resistance — maintaining an effective seal through heavy daily use and temperature cycling.
- Flame-Resistant and Moisture-Resistant: The seal material resists ignition and repels moisture, contributing to both fire-rated performance and weather protection.
- Broad Temperature Range: Rated from -76°F to 275°F, the 160UA performs reliably in extreme cold or high-heat environments without cracking, deforming, or losing its seal.
- Recommended for Air Infiltration Control: Specified by NGP as a recommended product for minimum air leakage and a tight perimeter seal — an important consideration for energy-code compliance and occupant comfort.
- Anodized Aluminum Finish: The anodized finish provides an attractive, durable surface that resists corrosion and complements standard aluminum door frames and hardware finishes.
- Head-and-Jamb Set Convenience: Sold as a complete perimeter set (1 head + 2 jambs) sized to the opening, simplifying ordering and ensuring a matched, continuous seal on three sides of the door.
- Made to Order in Five Opening Sizes: Available 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 accommodate standard single and double commercial door openings.

Pro-Tip for Perimeter Sealing
The NGP 160UA is surface-applied directly to the frame stop on three sides of the opening — head and both jambs. The slotted screw holes in the aluminum carrier allow you to fine-tune the seal's position against the door face after initial installation, ensuring consistent contact across the full perimeter. Stainless steel sheet metal screws are furnished with the set, so no separate fastener sourcing is required. For best results on fire-rated assemblies, verify that your door and frame assembly carries the appropriate UL listing for the rating required, and install in accordance with NFPA 80 and the door manufacturer's labeled instructions.
