This duct connection system is carried out through a Rectangular Flange, where the Flange is integrated into the duct wall using the same sheet to form the Rectangular Flange, which is completed with the quick and easy installation of four corner pieces that serve to accommodate 4 screws, guaranteeing the union between both ducts.

To ensure a better pressure between the ducts, a reinforcing clip is placed on the perimeter of the Rectangular Flange.

1. Cornerbacks:

a. It comes with 3/8” holes for the ducts to be attached using 4 screws.

b. They generate greater rigidity to the duct, since the TDF or TDC flange works as a Rectangular Flange system.

c. Made with lime sheet. 16.

2. Reinforcement clip

a. Used in TCD or TDF (Rectangular Flange) systems.

b. They are used in the perimeter of the duct according to its section.

c. Provides a uniform grip for Butylo tape.

d. They can be lime. 20 or 22
