PRO construction square 500 x 1000 mm painted — model 3-01-03-K3-105

PRO construction square 500 x 1000 mm painted — model 3-01-03-K3-105 is a right-angle measuring and marking tool with nominal dimensions 500 x 1000 mm. Designed for construction and carpentry, the square helps check and mark perpendicularity, lay out edges and verify the squareness of panels, frames and masonry. The painted finish provides protection against corrosion and everyday wear, making the tool suitable for both site and workshop use.

Advantages

The painted surface increases resistance to moisture and reduces the risk of rust, extending the tool's service life. Its large 500 x 1000 mm format enables accurate squaring of bigger workpieces and structures, while the rigid construction maintains right-angle accuracy during repetitive use. The instrument’s dimensions and visual contrast of the finish improve visibility of markings for clearer transfer of layout lines.

Suitable for

• Checking and marking perpendicularity of panels and frames
• Verifying squareness of masonry and wall openings
• Layout and marking for carpentry and furniture assembly
• On-site construction measurements and workshop fabrication

Key specifications

• Nominal dimensions: 500 x 1000 mm
• Shape: right-angle (L-shaped) square
• Finish: painted protective coating
• Primary use: measuring and marking perpendicularity and squareness
• Suitable environments: construction sites and workshops

How to use

Place one leg of the square firmly against the reference edge or face of the workpiece, ensuring full contact along the length of the leg. Use the other leg as a guide to draw marking lines or to check for gaps that indicate deviation from 90°. For larger panels, align the square at multiple points along the edge to confirm consistent squareness. Clean the painted surface after use to remove abrasive debris and prevent premature wear.

Usage recommendations

Store the square in a dry place and avoid dropping or bending the tool to preserve right-angle accuracy. When marking, use fine pencils or scribing tools to reduce wear on the finish. Inspect the edges periodically for nicks or dents, and repaint small damaged areas to maintain corrosion protection.
