National Guard Products 150UA Polyurethane Perimeter Weatherstrip Head-and-Jamb Set – Anodized Aluminum
National Guard Products (NGP) model 150UA is a screw-applied polyurethane perimeter weatherstrip set in an Anodized Aluminum finish with a black polyurethane insert. Each set includes one head piece and two jamb pieces sized to fit your opening, creating a continuous perimeter seal on the frame stop of hollow metal or wood fire-rated doors. The 150UA 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 — and is made to order with a typical lead time of 10–15 business days. UL-certified for both standard and positive-pressure fire door applications up to 3 hours on hollow metal and up to 90 minutes on wood doors, the 150UA delivers fire compliance, air-infiltration control, moisture resistance, and long-term durability in a single perimeter weatherstrip system.
High-Performance Polyurethane Perimeter Weatherstrip Features
- UL-Certified Fire-Door Compliance: Certified by UL to CAN/ULC-S104 and ANSI/UL 10B, and to ANSI/UL 10C 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 IBC, NFPA 80, and NFPA 252 positive-pressure requirements under ANSI/UL 10C — critical for stairwell, corridor, and exit-enclosure fire doors where pressurization systems are employed.
- Recommended Air-Infiltration Control: NGP designates the 150UA as a recommended product for minimum air leakage and a tight perimeter seal, supporting energy-code compliance and occupant comfort.
- Flame-Resistant Insert: The black polyurethane insert is flame-resistant, contributing to the product's fire-door listing and helping the seal maintain integrity during a fire event.
- Moisture-Resistant Construction: Designed to resist moisture intrusion at the door perimeter, protecting the frame, door edge, and adjacent finishes from water damage.
- Extreme Temperature Range: Rated from -76°F to 275°F, making the 150UA suitable for exterior openings subject to severe cold or high-temperature environments such as commercial kitchens and industrial facilities.
- Very Good Abrasion Resistance: The polyurethane compound provides strong abrasion resistance, helping the seal withstand repeated door contact cycles in high-traffic commercial openings.
- Excellent Memory and UV Resistance: Superior memory allows the insert to return to its original profile after compression; UV resistance preserves performance and appearance on doors with exterior exposure.
- High Tensile Strength: The polyurethane insert resists tearing and deformation, extending service life in demanding commercial and institutional applications.
- Aluminum Alloy 6063-T5 Carrier: The extruded Aluminum Alloy 6063, T5 Temper retainer provides a rigid, corrosion-resistant mount that holds the polyurethane insert securely against the frame stop.
- Anodized Aluminum Finish: The Anodized Aluminum surface treatment improves corrosion resistance and provides a clean, professional appearance consistent with standard commercial hardware finishes.
- Furnished Stainless Steel Screws: #6 x 3/4" stainless steel sheet metal screws are included, ensuring corrosion-resistant fastening compatible with the aluminum extrusion.
- Slotted Screw Holes for Adjustment: Screw holes are slotted to allow field adjustment of the weatherstrip position, ensuring optimal compression and seal quality during installation.
- Head-and-Jamb Set — Five Opening Sizes: Sold as a complete three-piece set (1 head + 2 jambs) pre-cut to your specified opening: 3'0 x 7'0, 4'0 x 7'0, 6'0 x 7'0, 6'0 x 8'0, or 8'0 x 8'0.

Pro-Tip for Perimeter Sealing
The NGP 150UA mounts directly to the frame stop using the furnished #6 x 3/4" stainless steel sheet metal screws. Because the screw holes are slotted, you can shift the weatherstrip laterally after initial fastening to fine-tune compression against the door face before final tightening — a key advantage on openings where the door stop profile or door edge alignment requires field adjustment. When ordering, confirm your opening size from the five available configurations so the head and jamb pieces arrive pre-cut and ready to install with no field trimming required on standard openings.
