Ruler KS Tools 300.0103 — precision metal measuring rule

The KS Tools 300.0103 precision metal measuring rule is a compact, durable tool for accurate linear measurements in workshops and on job sites. Manufactured by ks tools, this metal ruler provides clear graduations and a rigid profile that helps maintain straightness when marking, measuring and checking parts. Its compact length and solid construction make it suitable for general layout work, quick checks and repetitive measurements where a dependable, easy-to-handle ruler is required.

Advantages

The metal construction ensures resistance to bending and wear for consistent accuracy over time. Clear etched or printed graduations enable fast, precise reading of measurements. The slim, rigid profile offers good contact with measured surfaces and helps guide marking instruments. Compact dimensions make the ruler convenient to carry in a toolbox or pocket and suitable for tight spaces.

Suitable for

• General workshop measuring and layout tasks
• Checking straightness and alignment on components
• Marking and scribing lines on metal, wood and plastics
• Mechanics, technicians and DIY projects requiring precise linear measurement

Key specifications

• Material: metal construction for rigidity and durability
• Graduations: clear metric scale for direct millimetre reading
• Length: compact form factor suitable for close-quarters use
• Profile: slim, flat shape for good surface contact during measurement
• Finish: wear-resistant surface treatment for long-term legibility

How to use

Place the KS Tools metal ruler flat against the surface to be measured, aligning the zero point with the start of the measurement. Keep steady contact along the length of the ruler while reading the graduation marks or while scribing a line with a pencil, scriber or knife. For checking straightness, lay the ruler along the edge of the part and observe gaps or light passing beneath the ruler. Store the ruler in a dry place and avoid striking it against hard edges to preserve straightness and graduation legibility.

Usage recommendations

For best results, verify the ruler's straightness periodically against a certified reference or precision straightedge. Use a fine-point marking tool when transferring measurements and avoid excessive force that could deform the ruler or damage graduations.
