Stabila Heavy-Duty Box Level is the tool for framing, trim carpentry, and tile applications. Its unique BOX BEAM frame is designed to resist bending and warping, ensuring reliable accuracy every time. This level features one horizontal vial and two vertical vials that are crystal clear and readable from any direction without any loss in precision. The vial accuracy is for life, maintaining a tolerance of just .029 inches whether positioned vial-up or vial-down. With frame strength-to-weight ratio, this level is both durable and easy to handle. The removable endcaps allow for precise scribing in corners and enable readings in tight header and sill openings, while the rubber endcaps grip walls firmly without leaving marks. A metal hang hole provides convenient storage on-site, and large, comfortable rubber hand holes enhance grip and control. Each Stabila level is electronically adjusted, and the machine-milled faces ensure consistent measuring accuracy. The unbreakable acrylic vials are designed not to break, leak, or fog, ing long-lasting reliability. This level allows for top and side reading in both vial-up and vial-down positions, delivering accuracy possible. Sure-grip antislip wall pads keep the level securely in place during use. Its yellow electrostatic epoxy coating high visibility and resists mortar adherence and corrosion. The patented epoxy system locks the vials firmly into the frame to prevent any loss of accuracy, eliminating the need for readjustment. Model Number: 37424
