Angle Square AWTools 90° with Spirit Level 50 x 100 cm AW30109

Right-angle square from AWTools, model AW30109, measuring 50 x 100 cm and equipped with an integrated spirit level for quick alignment. The tool is made with a rigid profile to help maintain accuracy when checking and marking 90° angles on construction and woodworking tasks. Its size and fixed right-angle design make it suitable for squaring edges, installing frames, and setting out layouts on-site.

Advantages

The AWTools 90° angle square combines a stable aluminum profile with a built-in spirit level to reduce setup time and improve repeatability when transferring right angles. Its 50 x 100 cm dimensions provide a balance between reach and portability, and the solid construction resists twisting to keep measurements consistent. The integrated level allows quick visual verification of plumb or level alignment while squaring, reducing the need for separate tools.

Suitable for

• Checking and marking 90° angles on timber and sheet materials
• Installing door and window frames
• Laying out cabinetry and furniture carcasses
• On-site carpentry and general construction layout work

Key specifications

• Shape: Fixed 90° right-angle square
• Material: Rigid profile (aluminum or similar rigid alloy)
• Overall dimensions: 50 x 100 cm (height x base)
• Integrated spirit level for alignment checks
• Finish: corrosion-resistant surface treatment suitable for jobsite use

How to use

Place the angle square with its base against the reference surface so the assembled 90° corner aligns with the workpiece edge. Use the integrated spirit level to confirm plumb or level as required, and mark along the square’s edge to transfer an accurate right angle. For larger layouts, repeat positioning and re-check the level to ensure each mark is consistent. Store the tool flat or hung to avoid bending the profile.

Usage recommendations

Before each use, visually inspect the square for dents or bends and verify the spirit level bubble is centered when placed on a known flat surface. Clean debris from contact edges to maintain accuracy, and avoid using the tool as a pry bar or striking instrument to preserve the straightness of the profile.
