Mcdaniel Metals PL16X21X36-R6 Insulated Plenum R-6

Product Description

The MCDANIEL METALS PL16X21X36-R6 is a fabricated galvanized sheet metal plenum with an R-6 insulation rating, measuring 16 inches wide by 21 inches tall by 36 inches long. Constructed from 26-gauge galvanized steel, this plenum is designed for use in forced-air HVAC distribution systems where thermal performance and durability are required. The no-flange configuration suits applications where direct connection or custom fitting is preferred. Licensed HVAC technicians and sheet metal contractors install this component as part of supply or return air trunk line assemblies in residential and light commercial systems.

This plenum is suited for residential and light commercial forced-air HVAC installations requiring an insulated, non-flanged trunk box. The R-6 insulation value makes it appropriate for unconditioned spaces such as attics, crawlspaces, and mechanical rooms where thermal loss is a concern. Fabricated to order, this unit is built from galvanized sheet metal and arrives ready for installation into new construction or retrofit duct systems. Its silver galvanized finish resists corrosion in typical HVAC environments.

Key Features

• R-6 insulation rating reduces thermal loss in unconditioned spaces
• 26-gauge galvanized steel construction for corrosion resistance and structural rigidity
• No-flange design for direct connection or custom field fabrication
• Dimensions of 16 inches by 21 inches by 36 inches suit standard trunk line configurations
• Fabricated to order from galvanized sheet metal in the USA
• Insulated interior accommodates ductliner for additional thermal and acoustic performance

Compatibility

Designed as an OEM-style fabricated plenum replacement or new-installation component for residential and light commercial forced-air HVAC duct systems requiring a no-flange, insulated trunk box.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor in accordance with local mechanical codes and SMACNA duct construction standards. Shut down and lock out the air handling unit before connecting or modifying any plenum sections. Seal all joints with UL-listed duct sealant or mastic and support the plenum per manufacturer and code requirements. Do not use this plenum in applications requiring flanged connections without field modification by a qualified technician.
