With the Bosch Spirit Level 25cm, shelves and pictures are hanging straight in no time. This handy all-rounder delivers highly accurate results up to 0.05 mm/m thanks to horizontal and vertical bubble levels. Reading the level is easy, due to the bright fluorescent bubble liquid in the vials. This spirit level has a 0-22 cm metric scale, so no need to hunt around for a second tool as this one doubles up as a ruler. Alignment tasks can be done from flat or curved surfaces thanks to the level’s V-Groove and plane-milled bottom. This tool is tough: DIY enthusiasts will appreciate the robust, light aluminium composition, reinforced ribs and protective end caps with soft-grip slip stoppers as well as the practical marking hole, which can also be used to hang and store when jobs are done.
