The Wiha Electrician's Spirit Level is built for measuring and marking vertical and horizontal distances between flush boxes. End-to-end casing allows electricians to mark out lines without needing to stop. The ingeniously positioned linear scales ensure users can measure in comfort, even when viewing from above. Both level bubbles can be seen easily, even from an acute angle.Sliding marking points for boxes allow the spirit level to be adjusted to the marking distances required by local regulations. The variable distance marks for up to four flush socket boxes bring another advantage to electrical installation work. This means the level can be used in a wide variety of situations, even on an international level.Thanks to its compact dimensions, it is also perfect for portable use and can be easily stored away.
