We integrate diverse requirements from different usage scenarios, aiming to provide tools with multiple practical functions in a single device.
In this series, you’ll find classic scale rulers with multiple scales, as well as innovative scale rulers that incorporate protractors, L Squares, various curves, and different diameter holes. Originally developed for clothing design and pattern making, we later discovered their practicality in architectural design and engineering as well.
When it comes to quality, Keling upholds its tradition of excellence in craftsmanship to ensure the precision of our rulers’ scales. We employ patented techniques such as the sandwich-line printing technique to enhance durability and longevity, guaranteeing resistance to wear and tear.
