The Wiha Longlife® Electrician's Folding Ruler is able to perform several work tasks. It has an integrated holder function for cables between 3 and 7mm, making it easier to route them in difficult-to-access installation locations. There is also a box distance scale for up to 3 flush boxes and edge distance marking at 150mm.
Due to its orange colour, the ruler is quick and easy to find on sites, meaning no time is wasted searching for misplaced tools and so no need to replace lost ones.
