Stanley's commitment to producing precision-engineered, extremely accurate tools is most evident in its extensive line of layout tools, a category that includes nearly 60 different levels. So regardless of whether you're a do-it yourself homeowner or a professional contractor, Stanley has the tools you need to accurately measure, layout and mark virtually any piece. And the company designs and builds each layout tool with three criteria in mind: accuracy, ease of use and durability - a philosophy born a century and a half ago and still practiced today.
