Mcdaniel Metals SP10-48T Supply Plenum R-6 Insulated

Product Description

The MCDANIEL METALS SP10-48T is a factory-insulated sheet metal supply plenum designed for forced-air HVAC systems. 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.

The 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.
