Adjustable square Topex TOP-30C345 500 x 240 mm measuring square, adjustable framing tool

The Adjustable square Topex TOP-30C345 500 x 240 mm is a precision framing and inspection tool designed for marking, checking and transferring right angles. With blade dimensions of 500 x 240 mm, this measuring square provides a stable reference for verifying 90° angles on wood, metal and other construction materials. The tool features an adjustable alignment mechanism that allows you to set and lock the blade to obtain accurate squareness for layout and assembly tasks.

Advantages

This adjustable measuring square combines a large blade surface with fine adjustment to improve both speed and accuracy when marking and checking right angles. Its construction provides a firm contact with workpieces for reliable measurements, and the adjustable feature reduces the need for multiple fixed squares by allowing adaptation to different work situations. The tool is suited to both verification and layout, making it useful for framing, joinery and metal fabrication.

Suitable for

• Marking and checking 90° angles in woodworking
• Layout and squareness checks in metalworking
• Framing, joinery and cabinet making
• On-site construction alignment and inspection
• Transfer of reference lines and assembly layout

Key specifications

• Blade dimensions: 500 x 240 mm
• Adjustable alignment mechanism for fine squareness setting
• Rigid framing body for stable contact with workpieces
• Suitable for use on wood, metal and common construction materials

How to use

Place the square against the reference edge of the workpiece with the blade flush to the surface. Adjust the alignment mechanism until the blade attains the required squareness, then lock the adjustment to secure the setting. Use the blade edge to scribe or mark the material, or to verify that assembled components meet a 90° requirement. For layout transfer, align the blade with the existing reference line and move the square along the workpiece while maintaining firm contact.

Usage recommendations

Ensure surfaces are clean and free of debris before measuring, and periodically check the lock and adjustment for wear. Use the square on a stable support and avoid excessive force when tightening the adjustment mechanism to preserve accuracy. Store the tool in a dry place to prevent corrosion and maintain long-term performance.
