Lukjan RB206146 Straight Boot 6x14-6

Product Description

The LUKJAN RB206146 is a straight duct boot designed to transition from rectangular duct to a floor, ceiling, or wall register opening. This fitting connects trunk or branch ductwork to a standard register or grille in residential and light commercial forced-air HVAC systems. The straight boot configuration provides a clean, direct transition without offset, simplifying layout in tight framing cavities. It is typically installed by sheet metal workers or HVAC technicians during new construction or duct replacement projects.

This boot is suited for residential and light commercial forced-air heating and cooling applications. The 6x14-6 designation indicates a 6 inch round collar on one end transitioning to a 6 by 14 inch rectangular register opening, making it a common fit for floor registers in standard framed bays. It is used in both supply and return air duct systems depending on system design.
