SpecSeal® Quick Clip™ Perimeter Fire Barrier System is designed to accelerate the installation of curtain wall insulation for perimeter fire barrier systems. Ready-to-install with unique U-Brackets that clip onto mullions without direct screw attachment, this patented system features self-locking fasteners that secure insulation panels in place while providing superior safety and installation speed compared to traditional methods.

Key Features & Benefits

• Quick installation – fewer tools required with no fasteners needed for U-Brackets*
• Easy stiffener installation – L-shaped stiffener channel locks in place without mechanical attachment
• Increased safety – reduces cutting of sharp metal and eliminates impaling pins or spikes
• Patented technology – Patent Nos. 10,329,761, 10,329,762, with others pending
• Self-locking fasteners – push-in design for faster installation than screws or weld pins
• Strike installation – U-Brackets lock into place with simple mallet strike
• Wind tested – equivalent to 108 mph wind loading for 500 cycles (ASTM E1233)
• Fire resistance tested – meets ASTM E2307 standards for perimeter fire barrier systems
• UL Certified compatibility – designed for use with mineral wool and SpecSeal® brand coatings

*If mullion tolerances prevent snug fit, a screw may be required

System Components & Applications

U-Bracket System

• Clip-on design – attaches to mullions without drilling or screwing
• Multiple sizes – available for 2.5″, 3″, and 3.25″ nominal mullions
• Insulation compatibility – supports 2″, 3″, and 4″ insulated thicknesses
• Stiffener integration – receiving slot locks L-shaped stiffener channel in place
• Heat-treated galvanized steel – durable construction for long-term performance

Z-Bracket Applications

• Corner installations – used where U-Bracket installation is impractical
• Non-standard applications – flexible mounting for complex configurations
• Screw attachment – mechanical fastening to mullion when required
• Universal compatibility – works with all mullion sizes and insulation thicknesses

Installation Applications

• Curtain wall systems – primary application for perimeter fire barriers
• Vision glass areas – sealing around glazed assemblies
• Spandrel panel installations – fire barrier support for non-vision areas
• Floor-to-ceiling assemblies – comprehensive perimeter protection

Performance Standards & Testing

Fire Resistance Testing

• ASTM E2307 – perimeter fire barrier system testing
• UL Certified systems – compatible with mineral wool insulation
• SpecSeal® brand coatings – designed for use with company’s fire-resistant coatings

Wind Load Testing

• ASTM E1233 – wind cycling exposure testing
• 108 mph equivalent – wind loading for 500 cycles
• Structural integrity – maintains performance under extreme weather conditions

Safety Improvements

• Reduced cutting – eliminates need for onsite metal fabrication
• No impaling pins – safer than traditional hangers with outward-facing spikes
• Push-in fasteners – workers face fasteners inward for better safety
• Fewer tools – simplified installation reduces equipment requirements

Installation Advantages

Traditional vs. Quick Clip™ System

• Traditional method – requires cutting/fabricating light gauge metal onsite, screwing into mullions
• Quick Clip™ method – U-Brackets strike into place, self-locking fasteners install by hand
• Time savings – faster installation with fewer steps and tools
• Quality consistency – factory-manufactured components ensure uniform performance
• Safety enhancement – reduced sharp metal handling and safer fastener orientation
