The Manrose Round to Rectangular Male Adaptor is a compact and reliable ducting accessory designed to connect 100mm (4") round ducting to 110 x 54mm rectangular (flat channel) ducting. This short adaptor features male connections on both ends, allowing it to fit securely into standard rigid ducting systems.
Engineered to ensure minimal airflow resistance while offering a space-saving solution, this adaptor is especially useful in installations with limited ceiling or wall voids, such as in kitchens, bathrooms, utility rooms, and tight service runs. Its tough PVC construction provides durability and resistance to environmental stressors like temperature changes and moisture.

Male Connection Ends
Fits into both the round and rectangular ducts, simplifying installation and ensuring a snug, secure fit. -
Rigid and Durable PVC Construction
Made from high-quality PVC for long-lasting reliability, impact resistance, and resistance to moisture and moderate heat. -
