The STARTUL Master ST3510-035 steel try square is the longest model in the series, engineered for substantial projects requiring an extended, accurate reference. Built from solid steel, this robust tool is indispensable for checking squareness, marking long lines, and verifying angles on large panels, frames, and structural components in professional woodworking and metal fabrication.

Key Features:

• Extra-Long Precision Blade: The 350 mm blade, ground to a true 90° angle, provides an extensive reference edge for checking squareness and marking straight lines across large work surfaces.

• Integrated Dual-Purpose Scale: Features a double-sided scale with clear mm/cm graduations on the blade, allowing for direct measurement and layout, eliminating the need for a separate ruler.

• Heavy-Duty Steel Construction: Manufactured from durable steel for exceptional rigidity and stability, ensuring the square maintains its accuracy even when used on large, heavy workpieces.

• Versatile Angle Tool: Enables precise checking and marking of 90°, 45°, and 135° angles, making it highly useful for complex carpentry, cabinetry, and welding projects.
