The Goldblatt 36" Box Beam Level is crafted specifically for ease of use around a jobsite or for any at-home DIY project. This level features an advanced structural-aluminum frame that provides the highest level of durability, even over long-term use. The rubber end-caps are designed to reduce shock, and comfort grips are included to reduce fatigue. To improve ease of use, the patented verity-site design can be read from the front or the side and features a bright viewing-window that makes it easier to read than the average box level. The Goldblatt 36" Box Beam Level is accurate to .029 degrees or .0005 inches.
