It extends the allowable concrete pour depth by 4 inches, enabling installations in slabs up to 12 inches thick. This component is used in firestop sleeve applications where slab thickness exceeds the standard device range. Licensed firestop installers and general contractors working on commercial or multi-family construction typically install this adaptor during concrete forming and pour operations.\u003c\/p\u003e\n\u003cp\u003eThis adaptor is suited for concrete slab applications requiring extended pour depths in the 8-inch to 12-inch range. It accommodates both metallic and non-metallic versions of the 3M Fire Barrier Cast-In Device, making it useful across a range of pipe and conduit firestop penetration assemblies. It is sold individually and is typically specified on projects where fire-rated floor assemblies require deeper slab pours than the base device supports.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIncreases allowable concrete pour depth by 4 inches for slab thicknesses up to 12 inches\u003c\/li\u003e\n  \u003cli\u003eCompatible with both metallic and non-metallic 3M Fire Barrier Cast-In Device models\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for use with the 4-inch 3M Fire Barrier Cast-In Device\u003c\/li\u003e\n  \u003cli\u003eSupports proper firestop system performance in deep concrete slab applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the 4-inch 3M Fire Barrier Cast-In Device.

The adaptor must be properly positioned on the base Cast-In Device before concrete is placed. Always follow the published firestop system design and applicable building code requirements for fire-rated floor-ceiling assemblies. Do not modify or cut the adaptor, as doing so may void the firestop system listing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight Extension\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Slab Pour Depth\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.53 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051115165504\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: 7000133838\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347103318322,"sku":"7000133838","price":179.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310527913.jpg?v=1782097718","url":"https:\/\/voomisupply.com\/products\/3m-7000133838-fire-barrier-height-adaptor-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
