National Guard Products 161VDKB Vinyl Perimeter Weatherstrip Head-and-Jamb Set – Dark Bronze
The National Guard Products (NGP) 161VDKB is a Dark Bronze aluminum vinyl perimeter weatherstrip head-and-jamb set engineered to create a continuous, energy-efficient perimeter seal on commercial and institutional door openings. Each set includes one head piece and two jamb pieces, surface-applied to the frame stop with furnished stainless steel screws, 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. Manufactured from Aluminum Alloy 6063-T5 with a black Thermo-Plastic Vulcanizate (TPV) vinyl insert, the 161VDKB delivers UL-certified fire door compliance, positive-pressure rating, and reliable air infiltration control — making it a trusted choice for architects, contractors, and facilities managers specifying perimeter seals on hollow metal or wood fire-rated doors.
High-Performance Perimeter Weatherstrip Features
- UL-Certified Fire Door Compliance: 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 — keeping your opening code-compliant.
- Positive Pressure Certified: Also certified by UL to ANSI/UL10C and compliant with IBC, NFPA 80, and NFPA 252, confirming performance under positive pressure conditions for the same hollow metal and wood fire door ratings.
- Air Infiltration Control: Recommended by NGP as a tight-sealing perimeter solution that minimizes air leakage around the full door perimeter — supporting energy codes and occupant comfort.
- Aluminum Alloy 6063-T5 Extrusion: The rigid aluminum carrier provides dimensional stability and corrosion resistance in demanding commercial environments, with a nominal profile of 7/8" x 5/16" at .07" wall thickness.
- Thermo-Plastic Vulcanizate (TPV) Vinyl Insert: The black TPV sealing element is both flame-resistant and moisture-resistant, maintaining a consistent perimeter seal across a wide service temperature range.
- Extreme Temperature Range: Rated from -40°F to 250°F, making the 161VDKB suitable for exterior applications in harsh climates as well as interior fire-rated openings subject to heat exposure.
- Stainless Steel Fasteners Furnished: #6 x 3/4" stainless steel sheet metal screws are included, resisting corrosion and simplifying installation without additional hardware sourcing.
- Slotted Screw Holes for Field Adjustment: Pre-slotted mounting holes allow the installer to fine-tune the seal position against the door face after initial fastening, accommodating minor frame irregularities.
- Dark Bronze Finish: The Dark Bronze (DKB) anodized-look finish coordinates with popular dark bronze door frames and hardware, providing a finished, architectural appearance in commercial and institutional settings.
- Made to Order — Five Standard 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 cover single, pair, and oversized openings; please allow 10–15 business days for fabrication.

Pro-Tip for Perimeter Sealing
The NGP 161VDKB is designed for surface application directly to the frame stop, positioning the TPV vinyl insert to bear against the door face and create a continuous seal at the head and both jambs. Use the furnished #6 x 3/4" stainless steel sheet metal screws and take advantage of the slotted screw holes to make lateral adjustments before final tightening — this allows you to optimize seal compression across the full perimeter without redrilling. For fire-rated openings, always verify that the door, frame, and all perimeter seals are installed in accordance with the listing requirements of NFPA 80 and the applicable UL certification (ANSI/UL10B for standard pressure, ANSI/UL10C for positive pressure assemblies). Because the 161VDKB is made to order, confirm your opening size before placing your order to avoid delays on your project schedule.
