how do i attach a 3x10 elbow to a 3x10 stack

do i need to modify the elbow ?
Asked by: JR
You would create a "box" by assembling the halves of the stack duct. The box would be 3.25" x 10". Therefore, there would be an extra 1/4" of space around the elbow. Since sheet metal is malleable, you could use self-tapping sheet metal screws (they will self-drill a hole) and foil duct tape to secure and leak-proof the connection.
