External Ductwork Stiffener
Gebhardt Ductwork Stiffeners are fitted to the outside of ductwork to reinforce the ductwork and to reduce vibration. The stiffeners enable you to reinforce ductwork in a simple and cost-effective way. Pre-drilled holes ensure a convenient fixing. The stiffeners are also suitable to reinforce already fitted ductwork, as the stiffeners can be fitted to the completed ducts.
