Corrugated Dowel Tube (CDT) Circular
Circular Corrugated Dowel Tube (CDT) forms a clean, circular duct through concrete elements for services, post-tensioning or weight-saving voids, built as a flexible, spirally wound steel tube available in diameters from 40 mm to 150 mm. Its corrugated wall gives it the flexibility to follow gentle curves while resisting collapse during the concrete pour.
