The Malco DTSQ Duct Board Square is the HVAC pro’s essential companion for precise duct board layout. Crafted to pair seamlessly with Malco duct board cutting tools, this foldable 90° layout square streamlines every step from mark to cut, helping you work faster without sacrificing accuracy.

Why the DTSQ stands out

  • Lockable 90° open position for quick, reliable corners. Your lines stay true, reducing rework and wasted material.
  • Foldable design folds flat for compact storage in a bag or van, keeping your toolkit lean on crowded jobsites.
  • Integrated adjustable material thickness scale aligns with Malco’s three duct board cutting tool sizes, making it easy to match your layout marks to board thickness for clean, professional cuts.
  • Fits 1" and 1.5" duct board thicknesses (with the three-size scale), so you’re prepared for common HVAC fabrication jobs.
  • Rigid, lightweight aluminum construction stands up to jobsite conditions while staying easy to carry between tasks.
  • Designed to pair with Malco Duct Board Tools, delivering a cohesive, repeatable workflow from layout to finish.

Why it matters in the field

In duct board fabrication, precision isn’t optional—it's essential for airtight seams and clean installations. The DTSQ removes guesswork by providing a dependable reference for every cut. Set the thickness scale to your board, lock the square at 90°, and align your marks with confidence. Whether you’re assembling large plenums in the shop or trimming runs on-site, this tool helps you achieve consistent layouts, minimizing scrap and rework.

Who benefits most

Ideal for HVAC installers, sheet-metal fabricators, and service teams who frequently cut and assemble duct board. If you value efficiency, repeatable accuracy, and a compact kit, the DTSQ is a practical upgrade to your duct fabrication workflow.

Practical usage tips

  • Before you start, set the integrated thickness scale to match your board (including the 1" and 1.5" options) for alignment with your cut lines.
  • Open to 90° and lock firmly to establish a reliable baseline for multiple panels in a run.
  • Use the foldable design to store between jobs or when transporting; it folds down to occupy minimal space without compromising rigidity when deployed.
  • Pair with Malco duct board cutting tools to maintain a consistent workflow from layout to finish—less guesswork, more repeatable results.
  • For on-site use, keep the aluminum body clean and dry to preserve the accuracy of the thickness scale and the locking mechanism.

Built for the trades, the Malco DTSQ Duct Board Square delivers real-world performance—lightweight enough to carry every day, rugged enough to endure the jobsite, and precise enough to help you install ducts with professional-fit quality from start to finish.

Specifications

Malco DTSQ

•LOCKS INTO 90° FOR INSTANT, RELIABLE DUCT BOARD LAYOUT - NO GUESSING, NO DRIFT: The DTSQ snaps securely into a fixed 90° open position so your square stays true through every mark and cut; no shifting, no re-checking, no wasted material from a square that moves mid-layout. When the job is done, it folds flat for compact storage in your tool bag or van without taking up a dedicated slot.
•INTEGRATED ADJUSTABLE THICKNESS SCALE MATCHES YOUR MALCO CUTTING TOOL SIZE: The DTSQ's built-in adjustable material thickness scale is calibrated to align directly with Malco's three duct board cutting tool sizes so your layout marks account for material thickness automatically, without a separate calculation or measurement step. The result is cleaner cuts, tighter joints, and less scrap on every job.
•RIGID LIGHTWEIGHT ALUMINUM CONSTRUCTION BUILT FOR JOBSITE CONDITIONS: The DTSQ is machined from rigid aluminum that holds its shape and stays square under the daily wear of HVAC fabrication work; on the shop bench, in the back of a van, or on a commercial job site. Lightweight enough to carry all day without fatigue. Durable enough to outlast plastic alternatives that flex and lose accuracy over time.
•WORKS WITH 1-INCH, 1.5-INCH, AND 2-INCH DUCT BOARD - COVERS COMMON MATERIAL THICKNESSES: The DTSQ's adjustable thickness scale accommodates 1-inch 1.5-inch and 2-inch duct board, making it the only layout square you need regardless of which material thickness your job specifies. Switch between thicknesses with a quick scale adjustment; no second tool, no re-measuring from scratch.
•PURPOSE-BUILT TO PAIR WITH MALCO'S DUCT BOARD CUTTING TOOLS: Designed from the ground up to work alongside Malco's v-cut and straight-cut duct board cutting tools, the DTSQ eliminates the setup time and layout errors that come with using a general-purpose square on a specialized task. Whether you're fabricating in the shop or cutting on-site, the DTSQ keeps your measurements consistent and your cuts clean from the first panel to the last.
