NGP 5050C Anti-Ligature Silicone Bulb Fire & Smoke Seal — 300 ft Bulk Roll
The National Guard Products (NGP) 5050C is a commercial-grade anti-ligature silicone bulb perimeter gasketing engineered for fire-rated and smoke-barrier door assemblies where both life-safety compliance and ligature-resistant design are required. Supplied in a 300-foot bulk roll, the 5050C is a cost-effective solution for new construction projects, high-volume replacement programs, and facilities that demand a UL-listed fire and smoke seal on hollow-metal or aluminum door frames.
Why Silicone Bulb Gasketing for Fire & Smoke Applications
Silicone maintains its flexibility and compression set across a wide temperature range, outperforming vinyl seals that harden and crack in low-temperature environments. The bulb profile compresses uniformly against the door face, creating a continuous perimeter seal that resists air, smoke, and draft infiltration. Smoke is the leading cause of fire-related fatalities — a properly gasketed opening transmits significantly less smoke than an ungasketed door, directly supporting compartmentalization requirements under NFPA 80 and NFPA 105.
Anti-Ligature Design
The 5050C profile is specifically designed to meet anti-ligature requirements for behavioral health facilities, correctional institutions, psychiatric units, juvenile detention centers, and similar occupancies where exposed hardware attachment points must be minimized. The smooth, rounded silicone bulb eliminates protrusions that could be used as an anchor point, supporting compliance with facility safety guidelines without sacrificing fire and smoke sealing performance.
Key Benefits
- Fire & smoke rated — listed for use on fire-rated door assemblies per NFPA 80; supports positive-pressure (UL 10C) applications when installed as required
- Anti-ligature profile — smooth silicone bulb geometry reduces attachment-point risk in secure and behavioral health environments
- Silicone construction — maintains weathersealing and compression characteristics across a broad temperature range; will not harden, crack, or lose flexibility in cold climates the way vinyl seals do
- 300 ft bulk roll — ideal for multi-door projects, facilities maintenance programs, and contractor stock; reduces per-opening cost vs. pre-cut lengths
- Perimeter gasketing application — mounts to the door stop at the head and side jambs; seals door perimeter on closure
- Supports compliance with NFPA 80 clearance and gasketing requirements for fire door assemblies and NFPA 105 smoke and draft control
Typical Applications
- Behavioral health and psychiatric facility corridors and room doors
- Correctional and detention facility door perimeters
- Juvenile detention and secure residential treatment units
- Hospital and healthcare secure-unit door assemblies
- Fire-rated hollow-metal and aluminum door frames requiring smoke gasketing
- High-volume replacement and maintenance programs on rated openings
