Lukjan ob7205 Round-to-oval Straight Boot 5 Inches

Product Description

The LUKJAN ob7205 is a round-to-oval straight boot designed for HVAC duct systems that require a transition from a 5-inch round duct to an oval outlet. Fabricated from steel, this fitting provides a smooth, low-restriction airflow path through the transition point. The straight boot configuration simplifies alignment with adjacent ductwork, reducing installation time and the chance of misfit. At 0.5 pounds and measuring 10 inches in length by 5 inches in width by 10 inches in height, the ob7205 is compact enough for tight residential plenums and light commercial air distribution layouts. Licensed HVAC technicians and sheet metal installers are the primary end users for this type of fitting.

The ob7205 is suited for residential forced-air systems and light commercial HVAC installations where a round supply or return trunk must transition to an oval boot at a register or diffuser location. The straight boot orientation works well in floor, wall, or ceiling installations where the duct run approaches the outlet in a direct, perpendicular path. It is part of the LUKJAN Series 6012 round-to-oval boot lineup, engineered specifically for this transition geometry.

Installation Notes

Installation of this boot should be performed by a licensed HVAC technician or qualified sheet metal installer in accordance with applicable mechanical codes, including SMACNA duct construction standards. Shut down and lock out the air handling unit before fitting or sealing any duct component. Seal all joints with UL 181-rated mastic or foil tape to maintain system static pressure integrity. Do not over-compress the oval outlet collar when connecting to the register boot, as deformation can restrict airflow.
