Angle Ruler Grand GR-840 10 cm — precision measuring tool

Grand GR-840 is a 10 cm angle ruler designed for precise measurement and marking of angles in small-scale work. This handheld precision measuring tool offers a compact form factor that fits easily into a pocket or small toolkit, enabling accurate angle checks and layout work in carpentry, model making, DIY repairs and technical drawing. The 10 cm length balances portability and control, making it suitable for tasks where visibility and fine adjustment are important.

Advantages

The angle ruler provides reliable, repeatable angle measurement in a compact package that is easy to handle. Its short length and well-defined edges allow for precise placement against workpieces and templates. The device is lightweight and straightforward to use, facilitating quick checks and marking without the need for larger instruments. Materials and finish are chosen to reduce wear on measurement edges and to maintain accuracy over repeated use.

Suitable for

• Carpentry detail work and joint layout
• Model making and scale modelling
• Small repairs and DIY tasks requiring angle checks
• Technical drawing, sketching and template transfer

Key specifications

• Overall length: 10 cm
• Type: handheld angle ruler for small-scale measurements
• Primary use: measuring and marking angles
• Design: compact and portable for easy handling
• Accuracy focus: defined measurement edges for repeatable placement

How to use

Place the angle ruler against the workpiece so that its edges align with the surfaces or lines to be measured. Use the defined edges to transfer or mark the angle directly onto the material with a pencil or scribe. For comparative checks, align one edge with a known reference surface and read or mark the corresponding line. Handle the tool close to the measuring edge for improved control and keep the ruler steady while marking to preserve accuracy.

Usage recommendations

Store the ruler in a protective pouch or toolbox slot to prevent edge damage. Clean the measuring edges after use to remove dust or residue that could affect accuracy. Use a fine pencil or scribe for marking when high precision is required, and avoid applying excessive force that could deform the ruler or the workpiece.
