Ultraflex Transition Box 250×150 mm TB-10x06-05RE 64265A

Ultraflex TB-10x06-05RE is a specialized transition box designed for ventilation and air conditioning systems, enabling efficient connection of rectangular ducts measuring 250x150 mm (10x6") with round ventilation ducts of 125 mm (5") diameter ending with a so-called ring end. This product is used in HVAC installations where a change of duct cross-section from rectangular to round is necessary, e.g., when connecting ventilation units, heat recovery units, air distributors, or air distribution systems in residential, commercial, and industrial buildings. The box is made of high-quality materials ensuring durability and corrosion resistance, allowing long-term use even in demanding conditions. Installation is done by direct connection to ventilation ducts – the rectangular spigot allows tight fitting into the main duct, while the round outlet with ring end enables quick and secure connection of a flexible ventilation duct with a diameter of 125 mm. The box design minimizes air flow resistance, which translates into the efficiency of the entire ventilation system. The product is dedicated both to professional installers and service companies that value reliability and ease of installation.
