Who does not know this? You are at the construction site or in the workshop and need to mark a 45° or 60° angle, but you don't have a protractor at hand. Then this folding rule is an ideal helper for you: With the integrated angle scheme, you can easily and quickly create and transfer frequently used angles on the construction site. The yardstick is made of high-quality beech wood from sustainable forest management (PEFC). The hardened sheet steel joints with integrated steel spring ensure durability and precise engagement. Meter sticks from STABILA - always a good choice.
