The box measures 4 inches by 12 inches by 7 inches and ships with R8 insulation, equivalent to 2 inches of insulation thickness. The outer shell and collar are fabricated from hot-dipped galvanized steel conforming to ASTM A653 CS Type B, with the box body at 30 gauge and the collar at 28 gauge. A 2-inch flange and a 1\/2-inch drywall flange allow flush, secure mounting in finished ceilings. The 3-inch long collar with bead provides a positive register or diffuser seat. Sheet metal workers and HVAC installers use this box in residential and light commercial construction.\u003c\/p\u003e\u003cp\u003eThis ceiling box is suited for residential new construction and retrofit applications where insulated distribution boxes are required at ceiling register locations. The R8 insulation rating meets energy code requirements in climate zones where higher insulation values are mandated for duct components outside conditioned space. The top outlet configuration allows the box to connect directly to a supply duct dropping from above, while the bottom flange aligns with standard drywall ceiling finishes. The unit is sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eR8 insulation (2 inches thick) for energy code compliance in high-performance applications\u003c\/li\u003e\n\u003cli\u003eHot-dipped galvanized steel per ASTM A653 CS Type B for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eBox body at 30 gauge and collar at 28 gauge construction\u003c\/li\u003e\n\u003cli\u003e2-inch flange and 1\/2-inch drywall flange for flush ceiling installation\u003c\/li\u003e\n\u003cli\u003e3-inch long collar with bead for secure register or diffuser seating\u003c\/li\u003e\n\u003cli\u003eTop outlet and bottom flange configuration for straight drop from supply duct\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style ceiling box for residential and light commercial HVAC supply air distribution at ceiling register locations.

The supply air system should be shut down and the air handler de-energized before cutting into existing ductwork or framing a new opening. Follow local mechanical and energy codes for duct insulation requirements, box support, and ceiling penetration firestopping where applicable. Do not compress the insulation lining during installation, as compression reduces the effective R-value.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 4 x 12 x 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Rating\u003c\/strong\u003e: R8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Thickness\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot-dipped galvanized steel, ASTM A653 CS Type B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBox Gauge\u003c\/strong\u003e: 30 gauge (0.012 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollar Gauge\u003c\/strong\u003e: 28 gauge (0.015 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Width\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrywall Flange\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollar Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Location\u003c\/strong\u003e: Top\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOUTHWARK METAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 85r84127\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51383695147314,"sku":"85R84127","price":34.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674956.webp?v=1782604679","url":"https:\/\/voomisupply.com\/products\/southwark-metal-85r84127-insulated-ceiling-box-r8","provider":"Voomi Supply","version":"1.0","type":"link"}
