Fabricated from 22-gauge aluminized steel, it creates a clean, flush mounting point for dryer exhaust connections while recessing the dryer closer to the wall. The box measures 21 inches tall, 12.5 inches wide, and 4.375 inches deep overall, with a depth from nailing flange to rear of 3.5 inches. The top port is an oval measuring 4.875 inches by 3.125 inches. Weighing 4.03 pounds, this unit is manufactured in the USA and carries UL Classification for a 1-hour F-Rating. Licensed contractors and finish carpenters typically handle installation during new construction or remodel.\u003c\/p\u003e\u003cp\u003eThe db350 is suited for residential new construction and renovation projects where dryers are installed against framed interior or exterior walls. The recessed design allows the dryer to sit closer to the wall, reducing duct length and improving airflow efficiency. The box fits within standard 3.5-inch stud bays. Installers working on multi-unit residential or light commercial laundry rooms will find the tapered sides useful, as they allow multiple boxes to nest for storage and transport.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eUL Classified for a 1-hour F-Rating for fire-rated wall assemblies\u003c\/li\u003e\n\u003cli\u003e22-gauge aluminized steel construction resists corrosion and accepts paint without priming\u003c\/li\u003e\n\u003cli\u003eDeep drawn manufacturing process for consistent wall thickness and structural integrity\u003c\/li\u003e\n\u003cli\u003eExtension rim protrudes 0.875 inches from nailing flange for positive wall engagement\u003c\/li\u003e\n\u003cli\u003eEight 0.25-inch mounting holes, four per side, for secure fastening to framing\u003c\/li\u003e\n\u003cli\u003eGas port knock-out included on all units for combination gas-dryer installations\u003c\/li\u003e\n\u003cli\u003eTapered sides allow nesting of multiple boxes for efficient jobsite storage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style recessed dryer vent box for installation in framed walls with standard 3.5-inch stud bays in residential and light commercial laundry applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed contractor or experienced installer during rough-in framing or remodel work.
