Mcdaniel Metals PL121/2X16X36-R6 Insulated Plenum R-6

Product Description

The MCDANIEL METALS PL121/2X16X36-R6 is a 26-gauge galvanized sheet metal plenum with R-6 insulation, measuring 12.5 inches wide by 16 inches tall by 36 inches long. It is fabricated without a flange and ships as a single unit. This plenum is designed to serve as the central air distribution box in residential and light commercial forced-air HVAC systems, connecting the air handler or furnace to the main duct runs. At 17.25 pounds, the 26-gauge construction provides solid rigidity for static pressure handling. HVAC installers working with insulated ductwork systems will find this unit ready for integration into R-6-rated duct assemblies.

This plenum fits into new-construction and replacement applications where a no-flange, insulated sheet metal plenum is required. It is suited for residential forced-air systems and light commercial installs where the air handler or furnace discharges into a centrally located plenum box. The R-6 insulation value helps reduce thermal loss in unconditioned spaces such as attics, crawlspaces, and mechanical rooms. Fabricated from galvanized steel in the USA, it is intended for installation by licensed HVAC technicians following local mechanical codes.

Key Features

• Sold as a single unit (each)

Compatibility

Designed as an OEM-style fabricated replacement or new-construction plenum for residential and light commercial forced-air HVAC systems requiring a no-flange, R-6 insulated galvanized sheet metal plenum at 12.5 x 16 x 36 inches.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes and SMACNA duct construction standards. Shut down and de-energize the air handling unit or furnace completely before connecting or sealing the plenum. Seal all seams and joints with listed duct sealant or UL 181-rated tape to maintain system static pressure and insulation integrity. Do not compress or damage the insulation layer during handling or fastening.
