It installs directly to the formwork before the concrete slab is poured, creating a sleeve opening that accepts mechanical, electrical, or plumbing penetrants once the slab has cured and forms are stripped. The intumescent material expands when exposed to heat, sealing the annular space around plastic pipe to restrict fire and smoke passage. Rated for up to 3-hour fire protection, this device is used by fire-stop installers, general contractors, and licensed mechanical or plumbing contractors on commercial and multi-family residential construction projects.\u003c\/p\u003e\n\u003cp\u003eThis cast-in device is suited for new concrete floor construction where non-metallic piping must pass through a fire-rated slab assembly. It eliminates the need for a separate sleeve or post-pour core drilling in many applications. Typical installations include high-rise residential, healthcare, and commercial buildings where IBC and NFPA 101 compartmentalization requirements apply. The device handles 2-inch plastic pipe or conduit penetrations and is installed prior to concrete placement, making it a pre-pour solution for firestopping.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIntumescent construction expands under heat to seal 2-inch plastic pipe penetrations\u003c\/li\u003e\n  \u003cli\u003eRated for up to 3-hour fire protection in concrete floor assemblies\u003c\/li\u003e\n  \u003cli\u003eAttaches directly to concrete formwork before slab pour for clean integration\u003c\/li\u003e\n  \u003cli\u003eEliminates post-pour core drilling in compatible new-construction scenarios\u003c\/li\u003e\n  \u003cli\u003eAccepts mechanical, electrical, or plumbing penetrants after slab cure\u003c\/li\u003e\n  \u003cli\u003eSold individually, minimum order quantity of 12 units\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 2-inch non-metallic pipe or conduit penetrations through fire-rated concrete floor assemblies in new construction applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified contractors prior to concrete placement. Secure the device firmly to the form panel so it does not shift during the pour. After the slab cures and forms are stripped, route the pipe or conduit through the created opening per the applicable listed system instructions. Verify the installed assembly meets the required fire-resistance rating under IBC or the authority having jurisdiction before covering or concealing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePenetrant Type\u003c\/strong\u003e: Non-metallic (plastic) pipe\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: 0.95 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: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051115165368\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: 7100138821\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343008629042,"sku":"7100138821","price":214.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310527943.jpg?v=1782013624","url":"https:\/\/voomisupply.com\/products\/3m-7100138821-fire-barrier-cast-in-device-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
