Mcdaniel Metals PL16X193/4X36-R6 Supply Air Plenum R6 26GA

Product Description

The MCDANIEL METALS PL16X193/4X36-R6 is a factory-fabricated, insulated supply air plenum constructed from 26-gauge galvanized sheet metal with an R6 insulation value. Measuring 16 inches wide by 19.75 inches deep by 36 inches in length and weighing 21.75 pounds, this plenum is built to order for residential and light commercial forced-air HVAC systems. The galvanized steel construction provides corrosion resistance, while the integrated R6 insulation reduces thermal loss across the supply air transition. HVAC installers and sheet metal contractors specify this unit when a flanged connection is not required at the air handler or furnace outlet.

This plenum is suited for residential and light commercial forced-air installations where the supply air transition must be insulated to meet energy codes. The no-flange configuration accommodates job sites where the installer will fabricate or field-fit the connection to the equipment cabinet or duct system. It is used above gas furnaces, air handlers, and fan coil units as the primary transition between the equipment outlet and the main supply trunk. The silver galvanized finish and domestic manufacture make it a standard choice for new construction and equipment changeouts.

Key Features

• 26-gauge galvanized steel construction for durability and corrosion resistance
• R6 insulation value meets common energy code requirements for supply plenums
• No-flange design for field-fit or custom connection at equipment cabinet
• Fabricated to order — available in 24 GA, 26 GA, and 28 GA gauges
• Manufactured in the USA
• Accommodations for duct liner available per order specifications

Compatibility

Designed as an OEM-style fabricated replacement or new-installation supply air plenum for residential and light commercial forced-air HVAC systems requiring a 16 inches by 19.75 inches by 36 inches transition with R6 insulation and no flange.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor. Power down the air handler or furnace and confirm all electrical circuits are de-energized before beginning plenum work. Secure all duct connections with sheet metal screws and approved mastic sealant or UL-listed foil tape in accordance with local mechanical codes and SMACNA guidelines. Do not compress or damage the insulation during handling, as this reduces the effective R-value.
