Description
The TDC-25 flange is a transverse duct connector profile that slides over the edge of rectangular ductwork to form a rigid, airtight joint without the need for angle flanges or bolts.

Corner pieces and cleats complete the system, enabling fast, repeatable duct assembly that meets DW144 and Eurovent leakage class requirements.
