Mcdaniel Metals SP32-48T Supply Plenum 48 Inches R6

Product Description

The MCDANIEL METALS SP32-48T is a supply plenum designed for forced-air HVAC systems, providing a transition between the air handler or furnace and the supply duct network. Measuring 11 inches by 22.75 inches by 48 inches, this plenum handles airflow distribution at the start of the supply trunk. Constructed with an R6 insulation value, it is rated for residential and light commercial forced-air applications. Installation is typically performed by licensed HVAC technicians during new construction or equipment replacement. At 28 pounds, the unit is manageable for single-technician handling during rough-in work.

The SP32-48T fits into standard forced-air supply systems where a full 48-inch plenum run is required off the air handler or furnace cabinet. It is suited for residential new construction, retrofit installations, and equipment changeouts where the existing plenum must be replaced to match new equipment dimensions. The silver finish and rigid construction support clean duct connections to downstream supply branches. Contractors working in tight mechanical rooms or crawlspaces will find the 48-inch length appropriate for full-height vertical or horizontal supply runs.

Compatibility

Designed as an OEM-style supply plenum replacement for residential and light commercial forced-air HVAC systems requiring an 11-inch by 22.75-inch by 48-inch supply plenum with R6 insulation.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out power to the air handler or furnace before beginning plenum removal or installation. Seal all duct connections with listed duct sealant or UL 181-rated tape per local mechanical code requirements. Verify plenum dimensions against the equipment cabinet opening before securing to avoid air bypass leakage at the connection joint.
