Constructed from steel with a silver finish, this plenum measures 19.5 inches in length, 48 inches in width, and 11.25 inches in height, making it suited for full-width air handler or furnace installations. R-6 insulation is integrated into the assembly, reducing heat loss and limiting condensation on exterior surfaces. Licensed HVAC technicians and sheet metal contractors install this component as part of a supply-side duct system. At 34.592 pounds, the unit is a substantial, commercial-grade fabrication intended for permanent installation.\u003c\/p\u003e\u003cp\u003eThe SP10-48T supply plenum is used in residential and light commercial forced-air heating and cooling applications. It connects directly to the supply outlet of a gas furnace, electric air handler, or heat pump air handler, serving as the primary transition point from equipment to supply ductwork. Its 48-inch width accommodates wide equipment footprints common in horizontal or downflow installations. This plenum is appropriate for attic, basement, utility closet, and crawlspace installations where insulated plenums are required by code or energy efficiency standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIntegrated R-6 insulation reduces heat transfer and limits condensation on the plenum exterior\u003c\/li\u003e\n\u003cli\u003eSteel construction provides structural rigidity and long service life in permanent duct installations\u003c\/li\u003e\n\u003cli\u003eLarge 48-inch width suits wide air handler and furnace supply openings\u003c\/li\u003e\n\u003cli\u003e19.5 inches x 48 inches x 11.25 inches dimensions support high-volume airflow distribution\u003c\/li\u003e\n\u003cli\u003eManufactured in the USA\u003c\/li\u003e\n\u003cli\u003eProp 65 compliant — relevant for installations in California\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style supply plenum for forced-air residential and light commercial HVAC systems requiring an insulated rectangular plenum at the equipment supply outlet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or sheet metal contractor in accordance with local mechanical codes and SMACNA duct construction standards.
