When exposed to elevated heat during a fire event, the strip expands and forms a rigid char that seals the air space, slowing the spread of flames and noxious combustion byproducts into adjacent areas. The strip ships in a 50-foot roll, measures 1\/16 inch thick by 1\/2 inch wide, and features a factory-applied adhesive backing for fast, tool-free installation on prepared surfaces. Fire-stop contractors, glaziers, and door hardware installers are the primary tradespeople who specify and apply this product.\u003c\/p\u003e\n\u003cp\u003eThis intumescent strip is applied to the air gap between door leaves and frames in fire-rated door assemblies, and to the perimeter of fire-resistant glazing installations. It is suited for both new construction and retrofit applications where passive fire protection is required. The adhesive backing allows direct application to metal, wood, or composite door frame substrates without mechanical fasteners. It is black in color and sized to fit standard fire-door rebate dimensions common in commercial and residential construction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExpands under heat to seal gaps and form a char barrier against fire and smoke\u003c\/li\u003e\n  \u003cli\u003eAdhesive-backed for direct application without additional fasteners or adhesives\u003c\/li\u003e\n  \u003cli\u003e1\/16 inch x 1\/2 inch profile fits standard door frame rebate and glazing channel dimensions\u003c\/li\u003e\n  \u003cli\u003e50-foot roll length reduces splices and speeds installation on full door sets\u003c\/li\u003e\n  \u003cli\u003eBlack finish blends with painted or anodized door frame finishes\u003c\/li\u003e\n  \u003cli\u003eSuitable for both door frame and fire-resistant glazing perimeter applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style passive fire protection solution for fire-rated door frame assemblies and fire-resistant glazing installations where an intumescent seal strip is required by the door or glazing system manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by fire-stop contractors, glaziers, or certified door hardware installers in accordance with the door or glazing system manufacturer's listed instructions and applicable fire code requirements.
