National Guard Products 160UDKB Polyurethane Perimeter Weatherstrip Head-and-Jamb Set – Dark Bronze
National Guard Products (NGP) model 160UDKB is a polyurethane perimeter weatherstrip head-and-jamb set finished in Dark Bronze with a black polyurethane insert. Engineered for commercial and institutional door openings, this screw-applied perimeter seal is sold as a complete three-piece set — one head piece and two jamb pieces — sized to fit five standard opening widths and heights: 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 160UDKB mounts directly to the frame stop, delivering a tight, consistent seal around the full door perimeter while meeting demanding fire-door, positive-pressure, and air-infiltration requirements for both hollow metal and wood fire-rated assemblies.
High-Performance Perimeter Weatherstrip Features
- UL-Certified Fire-Door Rating (Standard Pressure): Certified by UL to CAN/ULC-S104 and ANSI/UL10B, 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.
- UL-Certified Positive Pressure: Certified by UL to ANSI/UL10C, complying with IBC, NFPA 80, and NFPA 252 for hollow metal fire doors rated up to 3 hours and wood fire doors rated up to 90 minutes — critical for stairwell and corridor applications where smoke containment is required.
- Aluminum Alloy Extrusion: The carrier is extruded from Aluminum Alloy 6063, T5 temper, providing a rigid, corrosion-resistant frame that holds profile geometry under repeated door cycles.
- Thermo-Plastic Vulcanizate (TPV) Insert: The black polyurethane-class TPV seal delivers very good abrasion resistance, tensile strength, memory, and UV resistance — maintaining an effective seal over the life of the installation.
- Flame-Resistant and Moisture-Resistant: The insert material resists ignition and does not absorb moisture, preserving seal integrity in fire-rated and exterior-adjacent door openings.
- Extreme Temperature Performance: Rated for a continuous temperature range of -76°F to 275°F, making it suitable for cold-storage, high-temperature, and exterior applications.
- Tight Air-Infiltration Control: Recognized as a recommended product for minimum air leakage and a tight seal around the full door perimeter, reducing energy loss and helping meet building envelope performance goals.
- Complete Head-and-Jamb Set: One head piece and two jamb pieces furnished per set, pre-cut to match the specified opening size — no field cutting required for standard openings.
- Slotted Screw Holes for Easy Adjustment: Screw holes are slotted, allowing field adjustment of the seal position against the door face during installation.
- Stainless Steel Fasteners Furnished: #6 x 3/4" stainless steel sheet metal screws are included, providing corrosion-resistant attachment hardware matched to the commercial installation environment.
- Dark Bronze Finish: The Dark Bronze anodized-look aluminum finish coordinates with commercial hollow metal frames and architectural hardware in dark bronze color families.
- Made to Order: This product is manufactured to order. Please allow 10–15 business days production lead time before shipment.

Pro-Tip for Perimeter Sealing
The NGP 160UDKB is designed to be surface-applied directly to the door frame stop — no routing or mortising required, making it a practical retrofit or new-construction solution. The furnished #6 x 3/4" stainless steel sheet metal screws fasten through slotted screw holes, which allow you to shift the seal strip slightly inward or outward during installation to achieve consistent contact pressure across the full height and width of the door leaf. For fire-rated assemblies, always verify that the installed configuration matches the conditions of the UL listing for the specific door type (hollow metal or wood) and the required fire rating (up to 3 hours for hollow metal; up to 90 minutes for wood). On positive-pressure-rated openings, proper perimeter contact is essential — the slotted holes make fine-tuning straightforward without redriving fasteners into fixed positions.
