National Guard Products 134SA Silicone Dense Bulb Perimeter Weatherstrip Set – Anodized Aluminum
National Guard Products (NGP) 134SA is a silicone dense bulb perimeter weatherstrip head-and-jamb set in an anodized aluminum finish with a black dense silicone bulb insert. 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. Engineered from Aluminum Alloy 6063 T5 and a synthetic rubber polymer silicone compound, the 134SA delivers a continuous, compression-fit perimeter seal around hollow metal and wood fire-rated doors — meeting some of the most demanding fire, smoke, positive pressure, and air infiltration standards in the commercial door industry. Because this is a made-to-order product, please allow 10–15 business days for fabrication and shipment.
High-Performance Silicone Perimeter Weatherstrip Features
- UL-Certified Fire Door Rating: 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 — making the 134SA a trusted perimeter seal for fire-rated door assemblies.
- Positive Pressure Certified: Certified by UL to ANSI/UL10C and compliant with IBC, NFPA 80, and NFPA 252, confirming performance under positive pressure conditions on hollow metal doors up to 3 hours and wood doors up to 90 minutes.
- Smoke & Draft Control Gasketing: Certified by UL to ANSI/UL10C and ANSI/UL1784 Category 'H'; complies with IBC and NFPA 105 for use on 'S' labeled positive pressure hollow metal fire doors rated up to 3 hours and wood fire doors rated up to 90 minutes — essential for corridors and stairwells where smoke compartmentalization is code-required.
- ANSI/BHMA A156.22 Certified: Independently certified to the American National Standard for Door Gasketing and Edge Sealing Systems and listed in the BHMA Certified Products Directory, confirming performance in heat and cold testing.
- FM200 and Halon Compatible: Specifically recommended for use in areas equipped with FM200 or Halon total-flooding fire suppression systems, where silicone's chemical resistance is a critical requirement.
- Extreme Temperature Flexibility: The dense silicone compound remains flexible across a temperature range of -81°F to 300°F, preventing compression set and seal failure in cold climates or high-heat environments.
- Ozone, UV, and Aging Resistance: The synthetic rubber polymer silicone formulation offers excellent resistance to ozone, ultraviolet exposure, and long-term environmental aging — reducing replacement frequency in exterior and high-exposure applications.
- Flame- and Moisture-Resistant Insert: The black dense silicone bulb is both flame-resistant and moisture-resistant, maintaining its integrity at doorway thresholds, exterior perimeters, and interior fire-rated openings alike.
- Excellent Memory and Flexibility: Dense bulb geometry combined with silicone's inherent elasticity provides consistent compression recovery, ensuring the seal re-engages fully every time the door closes.
- Head-and-Jamb Set Configuration: Sold as a complete three-piece perimeter set (one head, two jambs) sized to the door opening, eliminating field cutting of extrusions to length for standard openings.
- Adjustable Screw-Applied Installation: Slotted screw holes allow field adjustment during installation for precise alignment to the door stop. Furnished #6 x 3/4" stainless steel sheet metal screws resist corrosion and provide secure attachment to the frame.
- Durable Anodized Aluminum Housing: The 6063-T5 aluminum alloy extrusion with anodized finish resists corrosion, complements standard commercial door hardware finishes, and provides a rigid, stable carrier for the silicone bulb insert.
- Multiple 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 and double door applications across a wide range of commercial opening configurations.

Pro-Tip for Perimeter Sealing
The NGP 134SA mounts directly to the frame stop — no routing or mortising required. Before fastening, take advantage of the slotted screw holes to shift the extrusion slightly in or out until the silicone bulb makes full, even contact with the door face around the entire perimeter. Drive the furnished #6 x 3/4" stainless steel sheet metal screws snugly but not over-torqued, then cycle the door several times to verify consistent compression of the dense bulb without binding the door operation. For double-door openings (6'0 or 8'0 wide sets), align both active and inactive jamb pieces to the same depth on their respective stops before final tightening to ensure a uniform seal across the full opening width.
