How to Build Ductwork Framing

Build a frame around ductwork as a starting point for other projects, such as a base for built-ins or a pedestal for decorative items.

Step-by-Step Instructions:

Measure and Cut Boards

Measure the height from floor to ceiling and depth from the wall to the edge of the ductwork (or other obtrusive item). Cut two 2x4s to length.

Cut 2x4 Boards

Cut two 2x4s to the length of the floor to ceiling minus 3 inches. Each horizontal 2x4 will account for 1 1/2 inches of the total height.

Create a Box

Using the screw gun and screws, create a box out of the four newly cut 2x4s. Make sure the horizontal pieces are on the top and bottom of the box.

Create a Smaller Box

If the duct is not uniform in depth from the wall (if a footer has forced the bottom of your air duct out 1 1/2 feet from the wall), create a second, smaller, box.

Attach Square Frame

Again, measure the height and depth of the additional obstruction. Create a square frame from 2x4s according to these measurements. Screw or nail it into place against the existing frame.

Hammer Frame Into Place

If your ceiling joists are exposed, screw a scrap piece of 2x4 to the side of the joist to act as a brace for your frame (Image 1). Erect your frame and hammer it into place, using a level as you go to make sure the frame stays square (Image 2). The snug fit will hold it in place.

Use Frame for Other Projects

You can use the frame as a jumping off point for another project. Create another frame for the other side of the ductwork and drywall over it to create a knee-high pedestal for displaying decorative accents, or extend the frame to the edge of the wall to use as a base for a built-in.
