In duct board fabrication, small layout errors turn into wasted material, lost time, and frustrating rework. That’s why the tools used matter just as much as the cuts themselves.
The new Malco Duct Board Square was designed to deliver faster, more consistent layout capabilities to the duct board workflow—while integrating seamlessly with the Malco tools contractors rely on every day. Paired with Malco’s line-up of Duct Board cutting tools, this creates an all-in-one solution for your duct board fabrication needs.

In duct board fabrication, consistency matters just as much as speed. Trade pros are constantly balancing tight timelines with the need for accurate layouts and clean, repeatable cuts.
For contractors handling repetitive fabrication work day after day, maintaining precision across every cut becomes critical. Duct Board tools need to work quickly and help eliminate guesswork throughout the fabrication process. At the same time, crews can’t afford to sacrifice accuracy in the name of speed, especially when efficiency and finished appearance all depend on getting the layout right the first time.
That’s why having the right system of tools matters. Solutions that help streamline layout, improve repeatability, and support cleaner cuts can make a major difference in both productivity and material usage.
Malco’s duct board cutting tools were designed to bring greater consistency and efficiency to the duct board fabrication process. Engineered specifically for HVAC professionals working with duct board systems, the tools simplify duct board fabrication and provide consistent results.
Whether fabricating duct sections in the shop or adjusting in the field, trade pros need tools that fit naturally into their existing workflows. The Malco duct board square is lightweight and portable, making storage easy. Simply fold them up and go for on-the-go jobs.
The Duct Board Square wasn’t designed to work alone. It was designed to work specifically with Malco’s duct board cutting tools, eliminating the need to haul 3 different-sized squares to the jobsite.
Two Models. Maximum Efficiency.
