Work faster, easier and more accurately with Johnson's levels. This box level features solid block acrylic vials for durability that will never fog, leak or break, while the protective non-marring end caps protect the level from drops and impact. Because precision is essential, Johnson precision milled the edges to ensure frame accuracy. It has also been designed to make your job easier. When working in poorly lit areas, the SurroundView? vials reflect ambient light to keep them easy to read and the level's ergonomic hand grips provide a comfortable, sure grip every time.
