Lukjan DT01141048 Rectangular Duct Button Lock 48 in 14x10

Product Description

The LUKJAN DT01141048 is a 48-inch rectangular duct section with button lock seaming, designed for low-pressure supply and return air distribution in residential and light commercial HVAC systems. Measuring 14 inches by 10 inches in cross-section, this duct section connects into standard rectangular ductwork runs using the button lock seam for a secure, field-assembled joint. HVAC sheet metal installers and duct fabricators use this section as a straight run component in forced-air systems. The 48-inch length reduces the number of joints needed in long runs, helping to limit potential air leakage points.

This rectangular duct section is suited for trunk line extensions, branch takeoffs, and straight-run applications in residential forced-air heating and cooling systems as well as light commercial air distribution. It is typically installed in attics, crawlspaces, basements, and mechanical rooms where rectangular ductwork is specified. The 14-inch by 10-inch profile accommodates moderate airflow volumes common in residential and small commercial installations.

Key Features

• 48-inch section length reduces joint count in long straight runs
• 14 x 10 inch rectangular cross-section for standard residential and light commercial airflow
• Button lock seam construction for secure field assembly without additional fasteners at the seam
• Compatible with standard rectangular duct fittings, collars, and transitions of matching throat dimensions

Compatibility

Designed as an OEM-style replacement and new-installation component for standard rectangular duct systems using 14 x 10 inch throat dimensions in residential and light commercial forced-air HVAC applications.

Installation Notes

Rectangular duct sections are installed by licensed HVAC technicians or qualified sheet metal workers in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handling unit before making any connections to the duct system. Secure all longitudinal seams and transverse joints with the appropriate fasteners and seal with UL 181-rated mastic or metal foil tape to meet code requirements. Do not modify the button lock seam profile in the field, as this can compromise joint integrity and airtightness.
