Round to Rectangular Duct Adaptor 100mm to 225 x 25mm

The Manrose 225mm Round to 100mm Rectangular Adaptor is a robust transition piece designed to link 225mm round ducting to the 100mm rectangular system. Now produced from 95% recycled rigid PVC in a grey finish, it offers a durable and environmentally conscious solution for modern ventilation layouts. The moulded adaptor body maintains smooth airflow through the change in duct profile, helping reduce resistance across the system. It provides a secure, reliable fit between ducting types. Lightweight, impact‑resistant, and simple to install, this component is suitable for both residential and commercial extraction systems where a compact, low‑loss round‑to‑rectangular conversion is required.
