Flat Oval Spigot

The Flat Oval Spigot is a versatile connector for flat oval ducting, designed to join duct sections or attach ducts to components with a simple, slip-fit connection. Made from durable galvanised steel, it provides reliable structural stability and long-term corrosion resistance while maintaining smooth, efficient airflow. Ideal for straightforward duct-to-duct or duct-to-component connections, the Flat Oval Spigot makes installation quick and easy. For applications requiring a precise, rigid, and leak-resistant joint, the Flat Oval Flanged Spigot is available. 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
