The Manrose Round to Rectangular Adaptor is an essential fitting for modern ventilation systems, providing a quick and secure transition from 100mm (4") round pipework to 110 x 54mm rectangular flat channel ducting. Designed with space-saving efficiency in mind, this compact adaptor is ideal for use in areas where standard round ducting is too bulky, such as ceiling voids, wall cavities, and underfloor runs.

This component plays a key role in maintaining efficient airflow while allowing the installer to use low-profile ducting solutions without compromising on performance. Its short form factor and female connection ends allow for easy integration with standard rigid piping and flat channel systems in domestic or commercial settings.


Key Features

  • Efficient Round-to-Flat Transition
    Allows connection from a standard 100mm (4") round duct to 110 x 54mm flat channel ducting, ideal for confined spaces.
  • Compact Design
    Short length makes this adaptor suitable for tight or awkward installation zones while maintaining effective airflow.
  • Universal Compatibility
    Connects easily with most 100mm rigid round ducting and 110 x 54mm rectangular systems across the Manrose range and compatible brands.
  • Durable Construction
    Manufactured from high-quality, impact-resistant PVC plastic for long-term use and resistance to wear, moisture, and temperature fluctuations.
  • Lightweight and Easy to Install
    Weighs just 40g, enabling a simple, tool-free installation. Can be sealed with standard ducting tape or mastic sealant to enhance airflow efficiency and prevent leaks.
