Lukjan PL10121936A Custom Plenum 12.75x19.5x36 in

Product Description

The LUKJAN PL10121936A is a custom sheet metal plenum designed for use in forced-air HVAC duct systems. It measures 12.75 inches by 19.5 inches by 36 inches and includes a 0.5-inch hem along with a cap for a finished, secure connection. The hem adds structural rigidity to the edges and helps create a tighter seal at duct connections. This plenum is fabricated to custom dimensions, making it suitable for retrofit or new-construction installs where standard off-the-shelf plenums do not fit the required trunk layout. Licensed HVAC technicians and sheet metal contractors are the primary installers of this component.

This plenum is used in residential and light commercial forced-air heating and cooling systems. It serves as the central distribution box that connects the air handler or furnace to the main duct trunk. The custom 12.75 x 19.5 x 36 inch profile is built to fit specific equipment footprints or spatial constraints in mechanical rooms, attics, crawlspaces, and utility closets where a standard plenum would not clear the installation envelope.

Key Features

• Custom dimensions: 12.75 inches x 19.5 inches x 36 inches for non-standard applications
• 0.5-inch hem adds edge rigidity and supports a cleaner, tighter duct connection
• Includes cap for a fully enclosed, ready-to-install assembly
• Sheet metal construction typical of LUKJAN fabricated ductwork components
• Designed for forced-air supply or return plenum applications

Compatibility

Designed as an OEM-style custom fabricated plenum for residential and light commercial forced-air HVAC systems where a 12.75 x 19.5 x 36 inch plenum profile is required.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with local mechanical codes and SMACNA duct construction standards. Shut down and lock out the air handler or furnace before connecting or sealing the plenum. Secure all joints with sheet metal screws and seal with UL 181-rated mastic or foil tape to meet code requirements for duct leakage. Do not modify the hem or cap in ways that compromise the structural integrity of the connection point.
