Construction Square Best-Tools model 50120 120×60 cm b/w (aluminium frame)

The Best-Tools construction square model 50120 120×60 cm b/w (aluminium frame) is a large, rectangular measuring tool for carpentry and building layout. With a 120×60 cm blade and high-contrast black-and-white markings, it is designed to check and mark right angles, square panels, align frames and verify straight edges on-site. The aluminium frame provides rigidity while keeping the tool lightweight for transport between jobsites.

Advantages

The aluminium frame offers a balance of strength and reduced weight compared with heavier materials. The oversized 120×60 cm blade gives wide coverage for larger panels and assemblies, reducing the need for repeated repositioning. High-contrast black-and-white graduations improve visibility in varied lighting conditions, helping to speed up measuring and marking tasks. The square’s rectangular design stabilises against workpieces to provide consistent 90° checks and layout lines.

Suitable for

• Carpentry layout and checking right angles on frames and panels
• On-site construction measuring and marking
• Woodworking projects that require squaring large boards or assemblies
• Renovation tasks where quick verification of straightness and squareness is needed

Key specifications

• Blade dimensions: 120 × 60 cm
• Frame material: aluminium
• Markings: black-and-white high-contrast graduations
• Shape: rectangular construction square for 90° checks
• Intended use: measuring, marking and squaring in construction and woodworking

How to use

Place the square with one leg flush against the reference edge of the workpiece and the other leg across the surface to establish or verify a 90° angle. Use the high-contrast graduations to mark lines directly on the material or to transfer measurements. For squaring panels, align the square’s long edge along one side and mark the opposite edge or use it to guide a saw or router fence. Handle the tool by the frame to maintain contact with the workpiece and reduce measurement errors.

Usage recommendations

Store the square in a dry place and avoid dropping or striking the aluminium frame to preserve accuracy. Clean markings of dust and debris before use to maintain clear visibility of graduations. For best results on rough or uneven surfaces, rest the square against a stable reference or use a straight edge in combination with the square to improve repeatability.
