The Flat Channel 90 Degree Bend Rectangle to Round Socket White is a specialized ventilation fitting designed to transition and redirect airflow between rectangular flat channel ducting and round pipe systems within restricted building spaces. Engineered to negotiate tight 90-degree turns while simultaneously changing duct geometry, this component provides a crucial structural link in complex HVAC, extraction, and ventilation layouts.
 
Manufactured from high-grade, durable white PVC, the transition bend is lightweight, corrosion-resistant, and features smooth internal walls to minimize air turbulence and pressure drop. Its precision-molded profile ensures a secure, airtight push-fit connection with both standard rectangular flat channels and corresponding round spigots, maintaining reliable performance across concealed ceiling voids, wall cavities, and floor joists.
 
Essential for navigating architectural obstacles when installing kitchen cooker hoods, bathroom exhaust fans, or whole-house mechanical ventilation, this fitting simplifies transitions between different duct formats. Whether you are designing a new residential extraction network or retrofitting ductwork through tight structural spaces, the rectangle-to-round bend delivers professional-grade reliability and efficient airflow management.
