- Made from durable polycarbonate
- For marking out or checking 90° and 45° angles
Also with this angle you can reliably mark lines around edges without slipping. The material polycarbonate is transparent, which allows better control of the markings.
Functions of oblong and round marking holes
The manufacturer SHINWA developed this miter rule especially for markings on "2 x 4 Lumber". Here you can see the orientation of this product to the American market. We are talking about rough sawn lumber with the cross section of 2 x 4 inches (50, 8 x 101.6 mm). After drying and planing, about 1.5 x 3.5 inches (about 38 x 89 mm) remains. So, the two angled boards are exactly aligned with squared lumber of these dimensions, measuring 38 x 89 mm.
What do the elongated marking holes labeled 1/4 1/3 and 1/2 mean? Without further measuring, overleaves and two finger joints of different sizes can be marked in the simplest way.
The round marking holes allow screws to be placed accurately when the timbers are joined with screws only rather than traditional timber joints.
Planed squared lumber of these dimensions is hard to find in Europe. Even if you think away these very special additional features, this miter rule made of transparent material is a good choice for a variety of applications.
