It features 1.5 inches of ductliner insulation rated at R-6, providing thermal and acoustic performance at the supply register connection. The snap-rail flange simplifies grille and register attachment without separate fasteners. Licensed HVAC technicians use this box during new construction or retrofit duct rough-in work to terminate branch runouts at ceiling, wall, or floor register openings. The unit ships ready to install and integrates directly into standard low-pressure supply duct systems.\u003c\/p\u003e\n\u003cp\u003eThis register box is suited for residential new construction and remodel HVAC applications where insulated register boxes are required by energy codes or design specifications. It is sized for a 12 x 6 inch register opening and is compatible with trunk-and-branch supply duct layouts. The snap-rail flange design accommodates standard 12 x 6 inch grilles and registers. Installers working in climate zones that require insulated boots will find the R-6 lining meets common minimum insulation requirements for supply-side ductwork in conditioned or semi-conditioned spaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.5-inch ductliner insulation provides an R-6 thermal rating\u003c\/li\u003e\n  \u003cli\u003eSnap-rail flange allows fast, tool-light grille and register attachment\u003c\/li\u003e\n  \u003cli\u003e12 x 6 inch register opening fits standard residential supply grilles\u003c\/li\u003e\n  \u003cli\u003eSheet metal construction for durable, code-compliant duct termination\u003c\/li\u003e\n  \u003cli\u003eInsulated lining reduces condensation risk and radiant heat loss at the boot\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style insulated register box for standard 12 x 6 inch residential and light commercial forced-air supply duct systems.

Shut down the air handler and secure the system before connecting ductwork. Seal all duct connections with listed mastic or UL 181-rated tape per local mechanical code requirements. Do not compress or puncture the ductliner insulation during installation, as this reduces the effective R-value.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRegister Opening Size\u003c\/strong\u003e: 12 x 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Thickness\u003c\/strong\u003e: 1.5 inches ductliner\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation R-Value\u003c\/strong\u003e: R-6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 6.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Type\u003c\/strong\u003e: Snap-rail\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: MM Manufacturing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 641R6-12X6X7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M\u0026M MANUFACTURING","offers":[{"title":"Default Title","offer_id":51268092068146,"sku":"641R6-12X6X7","price":38.52,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308913383.webp?v=1780698888","url":"https:\/\/voomisupply.com\/products\/mm-manufacturing-641r6-12x6x7-insulated-register-box-r-6","provider":"Voomi Supply","version":"1.0","type":"link"}
