Ruth's sister 30cm Stainless Steel Double Sided Ruler 32.8cm internal power cable

30 cm stainless-steel ruler

This 32.8 cm stainless-steel ruler provides a 30 cm metric scale on one edge and a 12 inch imperial scale on the reverse. The 2.6 cm wide blade is laser-engraved for clear, wear-resistant markings. It suits workshop, engineering and classroom tasks that require both measurement systems in a single rigid tool.

Check scale and rigidity needs

Verify that a single 30 cm rule covers the longest dimension you measure regularly; longer workpieces will need an additional rule or tape. Confirm that a flat, inflexible metal blade is appropriate for the surfaces you mark, as it will not conform to curves or inside corners. Ensure the silver finish with black graduations offers sufficient contrast under your lighting conditions.

Fits tool kits and drawers

The 32.8 cm overall length slides into standard A4 tool trays, pencil cases or shallow drawers without protruding. Its double-sided layout removes the need to carry separate metric and imperial rules, freeing space for other layout tools. The stainless construction resists corrosion in humid shop environments, so it remains readable without protective coatings.
