Adjustable square Topex TOP-30C343 350×210 mm

The Adjustable square Topex TOP-30C343 350×210 mm is a bench and workshop tool designed for accurate right-angle marking and layout. The square has an adjustable head that locks securely to set and verify 90° angles and to transfer measurements between workpieces. Constructed for use in carpentry, joinery, metalworking and general workshop tasks, this tool combines a fixed blade and a movable stock to adapt to different marking widths while maintaining stable contact with the reference edge.

Advantages

The adjustable head allows fine setting and repeatable angle checks without relying on machined reference surfaces. The 350×210 mm dimensions give a useful balance between reach and control for medium-sized panels and assemblies. The locking mechanism secures the head in place to maintain measurement consistency during marking and layout operations. The tool’s construction supports straight, accurate lines and helps reduce cumulative errors when transferring or comparing edges.

Suitable for

• Carpentry and woodworking marking of boards, panels and frames
• Joinery layout work where accurate squaring is required
• Metalworking setup and simple angle verification
• General workshop tasks that need precise 90° transfer and checking

Key specifications

• Overall blade reach: 350 mm
• Stock length/height: 210 mm
• Adjustable head for setting and locking 90° angle
• Design: fixed blade with movable/adjustable stock
• Intended use: marking, squaring and transferring measurements

How to use

Place the blade firmly against the reference edge of the workpiece, adjust the head until the stock aligns at a true right angle and tighten the locking mechanism. Use the square to scribe a line along the blade or to transfer the perpendicular from one edge to the opposite edge. For repeated marks, confirm the head remains locked and reference the same contact points each time. When checking assembled components, rest the stock against one surface while the blade spans the adjoining face to visually and physically verify squareness.

Usage recommendations

Keep the reference edges of the blade and stock clean and free from burrs or debris to preserve accuracy. Store the tool in a dry place to prevent corrosion and periodically check the locking mechanism for wear. For critical precision work, verify the 90° setting against a calibrated square before use.
