Flat Oval 45° Lateral T-Piece

The Flat Oval 45° Lateral T-Piece is designed to provide a smooth and efficient branch connection within flat oval ducting systems. Its angled 45° lateral outlet allows airflow to split with reduced resistance compared to sharp branch connections, helping maintain consistent system performance and balanced air distribution. The flat oval profile is ideal for installations where ceiling or floor voids are restricted, offering the airflow capacity of round ductwork while fitting into lower-profile spaces. Fits into shallow ceiling voids where round ducting is too tall, maintaining the high-volume capacity required for efficient HVAC performance Fabricated from premium hot-dip galvanised steel for great structural rigidity and long-term corrosion resistance The seam provides a robust permanent seal Ideal for exposed-ceiling designs in commercial and high-end retail spaces Fittings supplied small end as standard to fit into straight duct Apart from stiffening requirements, flat oval ducts follow the same construction standards across all pressure ranges defined in DW144 In some cases, additional stiffening is required in the form of tie bars which are fitted in line with DW144
