Lukjan PS403303626U Double Joist Panning 33 in 26 Ga

Product Description

The LUKJAN PS403303626U is a 26-gauge double joist panning sheet used in residential and light commercial HVAC duct systems. Joist panning converts the space between floor joists into a supply or return air plenum, eliminating the need for a separate sheet metal duct in those runs. At 33 inches wide and built from 26-gauge steel, this sheet provides rigid, durable sidewall support for joist-bay air distribution. HVAC sheet metal installers and duct fabricators select this product when framing low-profile supply or return air pathways in wood-framed floor assemblies.

This joist panning sheet is suited for new construction and retrofit HVAC duct installations where floor joists serve as the structural boundary of the air passage. The sheet fits across a standard double-joist bay, and the 26-gauge thickness meets common residential duct construction requirements. Installers cut and fit the sheet along the joist bay, sealing edges to maintain airflow integrity through the duct system.

Key Features

• 26-gauge steel construction provides rigidity for joist-bay duct applications
• 33-inch width sized for double joist panning installations
• 36-inch length allows straightforward field trimming to fit framing variations
• Functions as supply or return air panning depending on system design
• Eliminates the need for round or rectangular branch duct in eligible joist bays

Compatibility

Designed as an OEM-style replacement and new-installation component for residential and light commercial HVAC duct systems using joist-bay panning as supply or return air distribution.

Installation Notes

Joist panning installation is typically performed by licensed HVAC sheet metal technicians or duct installers working under applicable mechanical codes such as SMACNA duct construction standards. Power down the air handling unit and associated controls before cutting into or modifying any duct section. Seal all sheet edges and lap joints with approved duct mastic or foil tape to prevent air leakage into the joist cavity. Ensure the joist bay is clear of insulation, debris, and obstructions before enclosing the panning run.
