A classic folding rule manufactured from downy birch with Swedish steel joints, affording thin sections and great flexibility. Scale with black figures on both sides, metric along the bottom edge and British imperial along the top edge.

Coated with a water-based protective lacquer for increased resistance to dirt and moisture.

The joints are heat-treated, coated and oiled at three points to ensure first-class performance.

Each folding rule section is checked twice during the production process using high-speed cameras.
