Origin Laser Tool Cornerstone Classic Laser Reference Level - Tim Litvin Origin Laser Tools Cornerstone Classic Laser Reference Tool - Tim Litvin


The Cornerstone Classic is CNC machined from 6061 aluminum, and tool steel. It is functionally identical to the Cornerstone Classic LE, but will save you some money.

Projecting three athermalized laser reference planes through patent-pending, diamond-turned aspheric optics, the Cornerstone Classic is powered by rechargeable Li-ion cells. Mount it on a tripod for a central, fixed plumb-level-square jobsite reference, or carry yours in a holster for instant personal use anywhere. The Cornerstone’s self-leveling function will improve the accuracy and speed of your layout work, making the building process much more efficient while saving you time and money. Its dual-grade (+/- 8.5%) functionality adds further versatility. And because the Cornerstone is built to last, using the highest quality materials and components available, it's an investment that will be saving you time and money for decades to come.
