Angle ruler KWB 067430 aluminum construction 90° for carpentry and metalwork

KWB 067430 is an aluminum construction angle ruler with a fixed 90° angle, designed to provide reliable right-angle measurement and marking for carpentry, metalwork and general construction tasks. The lightweight aluminum body offers a balance of durability and manoeuvrability, allowing accurate squaring of boards, frames and profiles. Its fixed 90° form ensures consistent results when checking corners, transferring lines or aligning components on site or in the workshop.

Advantages

The aluminum construction makes the angle ruler both corrosion-resistant and easy to handle, while maintaining sufficient stiffness for accurate measurements. The fixed 90° design eliminates the need for repeated adjustments and reduces the risk of angle drift. A compact, lightweight profile simplifies positioning on workpieces and enables quick marking and inspection without adding significant weight to the tool kit.

Suitable for

• Carpentry: squaring boards, marking cuts and checking mitre joints
• Metalwork: aligning profiles, checking welding angles and assembly fit-up
• General construction: verifying right angles on frames, drywall, and fixtures
• DIY and hobby projects requiring accurate 90° references

Key specifications

• Material: lightweight aluminum alloy body for durability and corrosion resistance
• Angle: fixed precise 90° geometry for squaring and right-angle checks
• Form factor: compact, flat profile for easy placement on boards and profiles
• Weight: lightweight design for comfortable handling and transport
• Use environment: suitable for workshop and site use under normal working conditions

How to use

Place the inside or outside corner of the angle ruler firmly against the edge of the workpiece so the two legs contact the surfaces to be squared. Hold the tool steady and use a pencil or scribe to mark along the ruler’s edge for a precise 90° layout line. For checking existing corners, align both legs with the adjacent surfaces and inspect for gaps or misalignment. Maintain firm, even pressure while transferring lines or checking fit to avoid slippage and ensure accurate results.

Usage recommendations

Keep the angle ruler clean and free of debris to maintain accurate contact with work surfaces. Store it in a dry place to preserve the aluminum finish. For best results when marking, use a sharp pencil or fine scribe and verify alignment visually before cutting or fastening.
