Ever wished you had your classic slide ductulator with you on-site, in a meeting or at your desk? Now you can. With DUCT, the simplicity and rapid sizing of the classic slide ductulator is now in your pocket.

DUCT uses the same rectangular equivalent method as your standard paper ductulator except all rectangular dimensions are recalculated from Huebscher’s equation.

Save time and money with DUCT as there is no typing in values like other ductulator apps. Just touch and move up and down to match the properties you want - just like the real thing. All size options and other performance values are visible at once, just like an original ductulator.

Available in SI units and Imperial units.

If you plan to use DUCT for work why not claim the cost of DUCT back as a work expense?
