Description
The Retrotec DU372 transparent flange is specifically designed for use with the Retrotec DucTester duct leakage measurement system. Thanks to its 13 9/16″ × 13 9/16″ (≈ 34 cm × 34 cm) format and its compatibility with Ø 10″ (≈ 25.4 cm) flexible ducts, it offers a fast, secure and visually controlled coupling, reducing installation errors and improving test efficiency.
Its transparent design allows the sealing and assembly to be observed during the test, providing additional reliability to the field technician. It is a must-have accessory for professionals in energy auditing, installation tightness and building quality control who already work with DucTester systems.
