TDF Ducks

TDF is a flanging system that consists of forming a flange profile on the duct ends, thus made out of a sheet from which the duct is fabricated. TDF is a 4 bolt duct connection system that eliminates time wastage. Rather than using separate connectors to assemble your system, TDF flanges are rollformed onto duct during the manufacturing process. This connection minimizes leakage and installation costs. These TDF flange eliminates the additional internal sealing around the edges of duct & thereby saves the labour & material.

Features:

Highly accurate flange profiles and components ensure ease of fitting and high-quality assembly. A Recessed groove on flange and radial groove on corner pieces for proper gasket seating Snap fit corner pieces to allow easy fitting at sites Flexibility to use suit-to-site pieces with ROLAMATEā„¢ slip-on flanges

Special Notes:

ROLASTAR does not subscribe to usage of red-oxide painted Angle Iron flanges as red-oxide is a known carcinogen. Conventional G.I. flanges have now become obsolete as they are totally substituted by Slip and Drive cleats system. TDF cannot be made below 250 mm size of the duct. We suggest to use C & S cleat instead of TDF.
