This set includes three box spirit levels measuring 600mm, 1200mm, and 1800mm, along with a 250mm torpedo spirit level. The box spirit levels have a milled underside for maximum flatness and high accuracy. They are equipped with three UV and shock-resistant vials at 180° and two at 90° angles. The rubber end caps provide extra shock resistance and there is a v-groove for leveling pipework. The torpedo level is made of die-cast aluminum with a powder-coated finish and strong magnets in the base. It features two vials set at 180° and 90° angles. Hang holes at both ends allow for easy storage.
