The RSA12 Adjustable LE Rafter Square is a large, 12-inch speed square with an adjustable fence, designed for superior performance in design, build quality, usability, and style. As the larger sibling of the RSA7 Adjustable, it's perfect for working with substantial lumber. Engineered for swift and simple marking and layout of roof trusses, its intelligent, locking fence ensures speed, ease, and repeatability. With numerous useful marking gauges on the blade, the RSA12 Adjustable LE excels in various carpentry and fabrication projects, particularly roofing and big lumber work. Curved scribe notches along the tool's length correspond to common lumber sizes, compatible with various marking tools. Manufactured in-house from premium T6 4mm thick aluminum, each tool is CNC machined to tight tolerances, maintaining right angle precision of +/- 0.008 throughout. The RSA12 features a protective 15um thick anodized surface, laser-marked graduation rulers, and deep-engraved degree lines for durability and precision. The adjustable, anodized aluminum fence is CNC machined, fixed via a nylon 66 bearing, and lockable with a stainless steel thumb screw for precise, repeatable cuts. Key features include a 12-inch recessed rule, fixed protractor gauge, rise and run gauge, scribe lines, and rafter length tables.
