Lukjan PL13202048 Adjustable Plenum 20x20x48

Product Description

The LUKJAN PL13202048 is an adjustable sheet metal plenum designed for use in forced-air HVAC duct systems. It serves as the central air distribution chamber that connects the air handler or furnace to the supply duct network. Measuring 20 inches by 20 inches by 48 inches, this plenum provides a rigid, sealable transition point for conditioned air before it enters branch ductwork. HVAC installers and sheet metal contractors use this component in both new construction and replacement applications where a durable, field-adjustable plenum is required.

This adjustable plenum is suited for residential and light commercial forced-air systems where the supply plenum must connect a central air handler or furnace to a trunk line or multiple branch ducts. The adjustable design allows on-site sizing adjustments to accommodate varying installation depths and equipment configurations. It is commonly installed above or below the air handler depending on system orientation and jobsite requirements.

• 20 x 20 x 48 inch nominal size accommodates a wide range of residential and light commercial air handler connections

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Disconnect and lock out all electrical power to the air handler or furnace before beginning plenum installation. Seal all joints with UL-listed foil tape or duct mastic per local mechanical code requirements to prevent conditioned air loss. Follow applicable SMACNA standards and local mechanical codes for plenum support, clearance, and connection methods.
