Lukjan DX231020 Shortway Vertical Angle 20x10 Duct

Product Description

The LUKJAN DX231020 is a shortway vertical angle duct fitting designed to redirect airflow within rectangular duct systems. Measuring 20 x 10 inches, this angle fitting handles direction changes along the short dimension of the duct, keeping static pressure loss to a minimum in tight plenum or inline routing scenarios. It is installed by sheet metal mechanics and HVAC technicians as part of a low-pressure supply or return air distribution system. The shortway geometry suits installations where space constraints prevent the use of a standard longway elbow.

This fitting is used in residential and light commercial HVAC duct systems where rectangular duct transitions or 90-degree direction changes are required. The 20 x 10 inch face size accommodates medium-capacity trunk lines and branch runs. Typical install locations include drop ceilings, utility closets, and mechanical rooms where the duct path must change direction without significant increase in duct height.

Key Features

• Shortway angle configuration minimizes the added height needed for direction changes in rectangular duct runs
• 20 x 10 inch face dimensions suit medium trunk and branch duct applications
• Vertical angle orientation supports standard low-pressure supply and return air systems
• Designed for use in HVAC duct and fittings assemblies per SMACNA guidelines

Compatibility

Designed as an OEM-style replacement or new-installation fitting for rectangular duct systems requiring a shortway 90-degree angle in the 20 x 10 inch size class.

Installation Notes

Installation is performed by licensed sheet metal mechanics or HVAC technicians. Secure all duct connections with appropriate sheet metal screws and seal joints with UL 181-listed mastic or foil tape per local mechanical code requirements. Shut down the air handling unit and verify the system is de-energized before modifying any section of the duct distribution system. Do not exceed the pressure class rating of the surrounding duct system when integrating this fitting.
