Polypipe Domus 50570 Round TO Rectangular Adaptor 125mm

This round to rectangular adaptor connects 125mm round ducting to standard rectangular duct, providing a practical solution for changing duct profiles within a ventilation system. It is commonly used where space or layout restrictions require a shift from round pipes to flat duct sections, such as above ceilings, behind cabinets, or in tight service voids.

On site, this adaptor enables installers to maintain airflow performance while adapting to different duct formats. Its compact shape and lightweight build assist with fitting in confined locations, supporting a tidy and efficient installation within domestic or light commercial ventilation setups.
