Cornerstone Classic LE


The Cornerstone is a lot more than just a laser level. By coupling high-accuracy servo-leveling with precision XYZ laser planes, the Cornerstone is like a Swiss army knife of laser tools. It can shoot a complete level plane, to do what a leveling rotator does… and then provide square foundation chalk lines, and then help with framing, and then with plumbing, and then with sheetrock, and then with cabinetry, and then with tile, and then with fixtures, and then with painting. It can do what a pendulum-based layout laser does, only better: it can project plumb-level-square laser “chalk lines” across every wall in a room as well on the ceiling and floor, all at once. It can also project a dual-grading plane up to 8.5%. All that functionality is packed into a rugged, holsterable tool. Someday may be other laser tools will do all this, but it’s a safe bet that they’ll never be this well built. This is a very versatile laser tool that’s built for keeps.

The Cornerstone Classic LE is our "Limited Edition" dual-grade model that takes a spare-no-expense approach to laser tool construction. The "LE" is marginally stronger than the standard Cornerstone Classic, due to its use of aircraft-grade 7075 aluminum and 440C stainless steel. These are costly, strategic materials that increase the overall strength and longevity of the already-rock-solid Cornerstone structure by about 25%. To put that in context, computer modeling says you could drive a truck stacked with three more trucks over a standard Cornerstone without deforming the structure; you could drive a truck stacked with four trucks over an LE. The LE is also hard-anodized, a more scratch-resistant finish. It's absurdly well built.

In a nutshell, if you could own just one laser tool: the Cornerstone Classic LE is the one you want. 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.
