It fits copper tube size tubing and seats in a 1-3\/8 inch hole punched or drilled in metal studs or track. The insert provides a barrier between the tubing and the metal framing edge, reducing wear and acoustic transmission while maintaining fire-rated wall assembly integrity. Licensed plumbers and mechanical contractors install this insert during rough-in when routing tubing through light-gauge metal framing.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for residential and commercial construction where tubing must penetrate metal framing rated up to 14 gauge. It is compatible with copper, PEX, and CPVC tubing in fire-rated wall, floor, or ceiling assemblies. Typical applications include multi-family residential, hotels, and commercial tenant improvements where fire-rated framing is standard. The 406-R is installed at the framing stage before drywall close-in.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFire retardant plastic construction suitable for fire-rated assemblies\u003c\/li\u003e\n  \u003cli\u003eFits a 1-3\/8 inch hole in metal framing for 1 inch copper tube size tubing\u003c\/li\u003e\n  \u003cli\u003eRated for use with metal framing up to 14 gauge\u003c\/li\u003e\n  \u003cli\u003eCompatible with copper, PEX, and CPVC tubing types\u003c\/li\u003e\n  \u003cli\u003eIsolates tubing from metal framing edges to reduce wear and vibration transfer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1 inch copper tube size copper, PEX, or CPVC tubing passing through metal framing up to 14 gauge in fire-rated environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or mechanical contractor during the rough-in phase. Power tools should be used to drill or punch a 1-3\/8 inch hole in the metal stud or track before snapping the insert in place. Verify that the insert is fully seated and that the tubing moves freely without contact with bare metal edges. Always confirm compliance with local fire-rated assembly requirements and applicable plumbing codes before close-in.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fire retardant plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTubing Compatibility\u003c\/strong\u003e: Copper tube size, PEX, CPVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRequired Hole Size\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Framing Gauge\u003c\/strong\u003e: 14 gauge metal\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: HOLDRITE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 406-R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLDRITE","offers":[{"title":"Default Title","offer_id":51383350362418,"sku":"406-R","price":37.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312672514.jpg?v=1782594162","url":"https:\/\/voomisupply.com\/products\/holdrite-406-r-fire-retardant-tube-insert-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
