The device mounts directly to the concrete formwork before the slab is poured, creating a formed opening that accommodates mechanical, electrical, or plumbing penetrants once the concrete has cured and forms are stripped. The intumescent material expands under heat, sealing the annular space around the pipe to help contain the spread of fire and combustion gases. Rated for up to 3-hour fire protection, it is used by plumbers, electricians, and mechanical contractors working in commercial or multi-story construction where code-compliant through-penetration firestop systems are required.\u003c\/p\u003e\n\u003cp\u003eThis cast-in device is intended for fire-rated concrete floor assemblies in commercial, institutional, and multi-family residential construction. It is suited for installations where metallic pipe, conduit, or similar 2-inch penetrants pass vertically through a concrete slab. The device is positioned and fastened to the form deck prior to the concrete pour, so no core drilling or after-the-fact sleeve installation is required. Mechanical, electrical, and plumbing trades working to IBC or local fire-code requirements rely on this approach to achieve rated through-penetration assemblies with minimal field labor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIntumescent design expands under heat to seal the annular space around 2-inch metallic penetrations\u003c\/li\u003e\n  \u003cli\u003eUp to 3-hour fire protection rating for fire-rated concrete floor assemblies\u003c\/li\u003e\n  \u003cli\u003eAttaches directly to concrete formwork before the slab pour, eliminating post-pour core drilling\u003c\/li\u003e\n  \u003cli\u003eCreates a formed sleeve opening for mechanical, electrical, or plumbing penetrants\u003c\/li\u003e\n  \u003cli\u003eWeighs 0.96 pounds, making single-trade installation practical without additional support\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 2-inch metallic pipe penetrations through fire-rated concrete floor assemblies in code-compliant through-penetration firestop applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanical, electrical, or plumbing contractors prior to the concrete pour. Secure the device firmly to the form deck at the intended penetration location before concrete is placed. After the slab has fully cured and forms are removed, route the pipe or conduit through the formed opening. Verify the completed assembly meets the applicable fire-resistance rating requirements of the local authority having jurisdiction and reference the manufacturer published listing for the specific penetrant type and assembly configuration.\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\u003ePenetration Type\u003c\/strong\u003e: Metallic\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\u003eAssembly Type\u003c\/strong\u003e: Fire-rated concrete floor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.96 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: 00051115165405\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: 7100138825\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343126069554,"sku":"7100138825","price":219.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310527939.jpg?v=1782017423","url":"https:\/\/voomisupply.com\/products\/3m-7100138825-fire-barrier-cast-in-device-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
