The STARTUL Master ST3515-060 is a heavy-duty, solid steel try square designed for large-scale construction, timber framing, and industrial fabrication. With a massive 600 mm blade and a robust 400 mm handle, this one-piece, all-metal tool provides a rigid and extremely accurate 90° reference for marking and checking squareness on beams, panels, and structural assemblies.

Key Features:

• Industrial-Scale Size: Features a substantial 600 mm blade paired with a long 400 mm handle, offering superior leverage and stability for working with large materials like timber, sheet metal, and structural components.

• Solid One-Piece Construction: Fabricated from a single piece of steel, ensuring maximum rigidity, durability, and permanent accuracy without the risk of joint failure.

• Clear Painted Scale: Equipped with a double-sided, painted scale featuring clear mm/cm graduations for convenient on-tool measuring and marking directly on the workpiece.

• Heavy-Duty Accuracy: The large contact surfaces of the blade and handle are precision-ground to a perfect 90° angle, essential for critical layout in framing, welding, and machining.

• Unmatched Stability: The long handle acts as a reliable reference fence, providing exceptional control and support when scribing lines or checking the squareness of large assemblies.
