Ductboard Square Tool

Ductboard Square Tool

• Function: A duct square tool is a guide that helps HVAC technicians make precise, straight, 90-degree angle cuts (and sometimes other angles like 15 and 22.5 degrees) on fiberglass duct board. This accuracy is crucial for ensuring the ductwork can be correctly folded, stapled, and taped to form a square, sealed, and efficient air flow system.
• Material: Made from lightweight, but durable, aluminum for corrosion resistance and longevity.
• Usage: It is used in conjunction with duct board cutting tools (often color-coded red and blue for V-groove and cut-off cuts, respectively) and a duct knife. The tool acts as a fence or guide, allowing the cutting tool to produce a clean, consistent cut or groove.
