Lukjan PL10121648A Custom Plenum 12-3/4x16x48 with Hem and Cap

Product Description

The LUKJAN PL10121648A is a custom sheet metal plenum section designed for use in ducted HVAC air distribution systems. Measuring 12-3/4 inches by 16 inches by 48 inches, this plenum box includes a 1/2 inch formed hem along its edges and a fitted cap, providing a finished, structurally sound unit ready for field installation. The hem reinforces the edges against flexing and helps create tighter, more consistent joints when connecting to supply or return duct systems. HVAC sheet metal installers and duct fabricators rely on this type of custom plenum to transition airflow from air handlers or furnaces into primary duct runs in both residential and light commercial applications.

This plenum is suited for new construction and replacement duct system installations where a specifically sized transition or plenum section is required. The 48 inch length accommodates longer trunk line connections or where a custom-length plenum is specified on a job drawing. The 1/2 inch hem and cap construction makes it appropriate for applications requiring clean, safe-to-handle edges and a closed-end configuration without additional field fabrication. It is intended for installation by qualified HVAC technicians or sheet metal workers following applicable mechanical codes.

Key Features

Compatibility

Designed as a custom-fabricated plenum section for use in residential and light commercial ducted HVAC air distribution systems requiring a 12-3/4 inch by 16 inch by 48 inch plenum with hem and cap.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal worker in accordance with local mechanical codes and SMACNA duct construction standards. Shut down and de-energize the air handling equipment before connecting or modifying any plenum or duct section. Secure all joints with appropriate fasteners and seal with listed duct sealant or metal tape per applicable code requirements. Handle edges with care even with the formed hem present, and use appropriate personal protective equipment when working with sheet metal components.
