Flat Oval Vertical T-Piece

The Flat Oval Vertical T-Piece is designed to create a vertical branch connection from a main flat oval duct run, allowing airflow to be distributed between different levels of a ventilation system. Its flat oval profile provides the airflow efficiency of round ductwork while fitting into shallow ceiling voids where space is limited. Engineered for reliable performance, this fitting enables smooth air distribution and integrates easily into flat oval HVAC duct systems used in commercial, retail and industrial environments. 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
