Hi CS67,


The first step is to layout your plan for the new duct work. Where, how long and what size are you going to use?


Once you have the plan in place, you can purchase the actual duct and adaptors to tap into the existing duct work for your new branches.


The adaptors have flanges designed to allow attachment of the adaptors to the existing ductwork.


Just cut the appropriate size hole, insert the adaptor and screw it into place with sheet metal screws through the flange, or in the case of flexible ductwork, secure the adaptors with foil or duct tape.


Metal duct can be cut with a jig saw or reciprocating saw, flexible duct can be cut with a utility knife or sheers.


Install the new duct, using hangers as need and then install your vents and grills at your termination points.


Be sure to locate your vents so you have complete coverage of the entire area, and place them so you do not create drafts.

It"s easier to cut hole in metal duct with aviation snips (left and right hand cutting) or with a power unishear or doublecut saw. Start by drilling  a hole with a 3/4" unibit.
