Installed before the concrete slab is poured, the device attaches directly to the form and creates a pre-formed opening for mechanical, electrical, or plumbing penetrants once the slab has cured and forms are stripped. The intumescent material expands under heat to seal the annular space around the penetrant, providing up to 3 hours of fire protection. Licensed contractors working under fire-stop or firestop inspection programs typically specify and install this product.\u003c\/p\u003e\n\u003cp\u003eThis device is suited for commercial and industrial construction applications where concrete floor decks require through-penetration firestop protection. It accommodates metallic pipes, conduit, and similar round penetrants routed through fire-rated concrete floor slabs. The cast-in installation method allows the firestop to be integrated during the concrete pour rather than retrofitted afterward, making it well suited for new construction projects where schedule and inspection continuity are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIntumescent material expands under elevated heat to seal around metallic penetrants\u003c\/li\u003e\n  \u003cli\u003eDesigned for 6-inch metallic penetrations through fire-rated concrete floor assemblies\u003c\/li\u003e\n  \u003cli\u003eProvides up to 3 hours of fire protection\u003c\/li\u003e\n  \u003cli\u003eCast-in installation attaches directly to the form before the concrete pour\u003c\/li\u003e\n  \u003cli\u003eCreates a finished opening for mechanical, electrical, or plumbing penetrants after slab cure\u003c\/li\u003e\n  \u003cli\u003eEliminates the need for retrofit firestop work at this penetration type\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 6-inch metallic penetrations through fire-rated concrete floor assemblies in new construction applications where a cast-in firestop solution is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by attaching the device to the concrete form prior to the slab pour; verify positioning and penetrant routing before concrete is placed. After the slab has cured and forms are removed, route the appropriate mechanical, electrical, or plumbing penetrant through the formed opening. Work must comply with applicable fire-stop provisions of the International Building Code and be inspected by the authority having jurisdiction. Do not modify or cut the intumescent collar, as alterations may void the fire rating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePenetration Size\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePenetration Type\u003c\/strong\u003e: Metallic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAssembly Type\u003c\/strong\u003e: Fire-rated concrete floor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFire Protection Rating\u003c\/strong\u003e: Up to 3 hours\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100138822\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343048999218,"sku":"7100138822","price":139.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310527906.jpg?v=1782014853","url":"https:\/\/voomisupply.com\/products\/3m-7100138822-fire-barrier-cast-in-device-6-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
