Built from hot-dipped galvanized steel per ASTM A653 CS Type B, this unit features a top outlet with a bottom flange configuration. The box shell is formed from 30-gauge (.012 inch) steel, while the collar uses 28-gauge (.015 inch) steel for added rigidity. R8 insulation (2 inches thick) is factory-applied, making this unit suitable for installations where thermal performance and energy code compliance are required. The 4-inch depth box and 3-inch long collar with bead provide a stable, consistent connection point at the ceiling plane.\u003c\/p\u003e\n\u003cp\u003eThis ceiling box is used in forced-air HVAC systems where a ceiling-mounted supply outlet is required. The bottom flange sits flush against drywall or ceiling board, with a 1\/2-inch drywall flange and a 2-inch flange on the standard side. The overall height of the assembly is 7.5 inches, accommodating typical joist-bay installations. HVAC installers and sheet metal contractors use this box in new construction and renovation projects where insulated ceiling diffuser boxes are specified for attic-side duct connections. The nominal duct opening is 4 inches x 10 inches x 6 inches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot-dipped galvanized steel construction per ASTM A653 CS Type B for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eR8 insulation (2 inches thick) factory-applied to meet thermal performance requirements\u003c\/li\u003e\n  \u003cli\u003e30-gauge (.012 inch) box body with 28-gauge (.015 inch) collar for structural integrity\u003c\/li\u003e\n  \u003cli\u003e3-inch long collar with bead for secure duct connection\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch drywall flange and 2-inch bottom flange for flush ceiling installation\u003c\/li\u003e\n  \u003cli\u003e7.5-inch overall height fits standard joist-bay depth requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation ceiling box for residential and light commercial forced-air HVAC duct systems requiring a top-outlet, bottom-flange insulated ceiling box with a 4-inch x 10-inch x 6-inch opening.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or sheet metal contractors. Power down the air handler and close the system dampers before securing the box in the ceiling cavity.
