National Guard Products 161VA Vinyl Perimeter Weatherstrip Head-and-Jamb Set — Anodized Aluminum
National Guard Products (NGP) model 161VA is an anodized aluminum vinyl perimeter weatherstrip set featuring a black TPV (Thermo-Plastic Vulcanizate) vinyl insert designed to create a tight, durable seal around the full perimeter of 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 161VA is UL-certified for application to hollow metal fire doors rated up to 3 hours and wood fire doors rated up to 90 minutes, and carries UL positive-pressure certification to ANSI/UL10C. This is a made-to-order product with a lead time of approximately 10–15 business days.
High-Performance Vinyl Perimeter Weatherstrip Features
- UL Fire-Door Certified (Standard & Positive Pressure): Certified by UL to CAN/ULC-S104 and ANSI/UL10B, and to ANSI/UL10C for positive pressure, complying with NFPA 80 and NFPA 252 for hollow metal doors rated up to 3 hours and wood doors rated up to 90 minutes — making the 161VA a code-compliant choice for rated door openings in commercial and institutional construction.
- Aluminum Alloy 6063-T5 Extrusion: The carrier is extruded from 6063 T5 temper aluminum alloy at 0.07” wall thickness, providing a rigid yet lightweight frame that resists warping and corrosion over the life of the opening.
- Thermo-Plastic Vulcanizate (TPV) Vinyl Insert: The black vinyl seal is manufactured from TPV, a flame-resistant and moisture-resistant compound with a tested temperature range of −40°F to 250°F — maintaining consistent compression and sealing performance in extreme climates and high-heat fire-door applications.
- Full Head-and-Jamb Perimeter Set: Sold as a complete three-piece set (one head + two jambs) sized to the selected door opening, eliminating the need to source and cut individual lengths on the jobsite.
- Five Standard Opening Sizes: Available factory-cut for 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 openings, covering the majority of single and pair commercial door applications.
- Recommended for Minimum Air Infiltration: NGP designates the 161VA as a recommended product for minimum air leakage and a tight seal around the door perimeter, contributing to building envelope performance.
- Slotted Screw Holes for Field Adjustment: Mounting holes are slotted to allow fine positioning adjustments during installation, ensuring consistent contact between the vinyl seal and the door face without shimming or re-drilling.
- Stainless Steel Fasteners Furnished: #6 x 3/4” stainless steel sheet metal screws are included, resisting corrosion in both interior and moisture-prone exterior vestibule applications.
- Anodized Aluminum Finish: The anodized finish provides an attractive, corrosion-resistant surface compatible with standard commercial door frame finishes and consistent with mill aluminum hardware aesthetics.
- Economical Perimeter Seal Solution: NGP positions the 161VA as an economical perimeter weatherstrip, delivering fire-door-rated sealing performance at a cost-effective price point for new construction and renovation projects.

Pro-Tip for Perimeter Sealing
The NGP 161VA is designed for surface application directly to the frame stop. The slotted screw holes allow the installer to shift the weatherstrip slightly in or out for optimal vinyl contact with the door face before final fastening. The furnished #6 x 3⁄4” stainless steel sheet metal screws are sized for direct attachment to standard hollow metal or wood frame stops without pre-drilling pilot holes in most applications. Install the head piece first, then fit the jamb pieces to meet it cleanly at the corners for a continuous perimeter seal. Because the 161VA is made to order in the selected opening size, verify the exact rough-opening dimensions before placing the order to ensure the factory-cut lengths arrive ready to install.
