Mcdaniel Metals TR2-18T Transition Plenum R-6 Insulated

Product Description

The MCDANIEL METALS TR2-18T is an insulated transition plenum designed to connect duct openings of differing sizes in forced-air HVAC systems. It transitions from a 19 x 14 inch opening to a 23 x 21 inch opening, making it a practical solution for air distribution layouts where duct geometry changes between the air handler or furnace and the main trunk line. The unit ships with R-6 insulation, which helps reduce heat gain and loss through the plenum body. At 11.22 pounds, it is a substantial sheet metal component intended for professional installation in residential or light commercial ductwork systems.

This transition plenum fits applications where a duct system requires a step-up or step-down connection between two rectangular openings. It is suited for new construction and retrofit installations in residential forced-air systems, particularly where the equipment cabinet outlet does not match the existing trunk duct dimensions. The R-6 insulation rating makes it appropriate for installations in unconditioned spaces such as attics, crawlspaces, and garages where energy code compliance for duct insulation is required.

Key Features

• Transitions from 19 x 14 inches to 23 x 21 inches to connect mismatched duct openings
• R-6 insulation factory-applied to reduce thermal loss in unconditioned spaces
• Sheet metal construction for durability and long service life
• Weighs 11.22 pounds for stable, secure installation in duct systems
• Suited for residential and light commercial forced-air HVAC applications

Compatibility

Designed as an OEM-style transition plenum for rectangular duct systems requiring a connection between a 19 x 14 inch opening and a 23 x 21 inch opening in forced-air HVAC installations.

Installation Notes

Installation should be performed by a licensed HVAC technician. Power down the air handling equipment at the disconnect before beginning duct work. Seal all joints with UL 181-rated mastic or metal-backed tape in accordance with local mechanical codes and ACCA installation standards. Support the plenum per local code requirements to prevent stress on adjacent duct connections.
