Let's build your duct run

How to use the duct builder

• Pick your duct size at the top. Every piece updates to match.
• Click + Add a Part to place your first piece. A Field Installed Riser is a good start.
• Click a blue + on any open end to connect the next piece.
• Click a piece to select it, then rotate it, flip its ends, set its length, or delete it.
• Drag to orbit, right-drag (or two fingers) to pan, and scroll or pinch to zoom. Use the cube or the Front / Side / Top buttons to look along an axis.
• See Dimensions shows the overall width, depth and height. Centerline draws the duct centerline and measures from the center of the first piece to the center of the last piece (C/L to C/L). When one end is an open end rather than a centerline, it reads C/L to end.
• V clamps, sealant and suggested supports are added to your parts list for you.
