Rectangular Duct Profiles & Corners

Rectangular ductwork profiles and corners are the means to join lengths of ductwork together and enable a near airtight seal between the pieces. Typically, this would be done using four lengths of profile each connected with a corresponding corner producing a frame. The frame is then attached to the next frame and so on.
