Through-Hole Leveling Jacks are designed for precise leveling at a desired clamping point. Clamping is achieved by tightening a bolt inserted through the workpiece and through the inside Diametermeter of the leveling jack, after the desired level is set. The static load due to tightening the mounting bolt also securely locks the jack's rotation. These leveling jacks consist of a threaded upper sleeve and a tapped lower sleeve, with a fine thread that allows precise setting. An anti-rotation disk serves as a positive limiter for maximum height. A spanner wrench can be used for additional leverage.
