Introducing the Detachable Stainless Steel Round Head Rotary Protractor Angle Ruler. This high-precision tool is made from durable stainless steel and comes in a sleek silver color. With a length of 15cm and an angle range of 0° – 180°, it’s the perfect size for a variety of tasks.
This protractor is not just a tool, it’s a game-changer for anyone involved in wood building, mapping, designing, and more. It’s designed for simple measurements of both angle and length. The dial reads from 0-180 degrees, and the foot-long strip is divided into 15cm sections.
One of the standout features of this protractor is its laser engraving, which ensures clear and easy reading. The angle ruler is combined with a screwing mechanism, allowing for easy disassembly.
Using this protractor is a breeze. Here’s how:
1. ZERO: Loosen the screw and turn the handle ruler until it’s level with the bottom of the main plate. Make sure the start line is on the 0 position. This allows you to calibrate the protractor for accuracy.
2. Measure Angle: Loosen the screw, place the subject on the bottom of the main plate and align the handle ruler with it. Tighten the screw and read the base line position on the main plate.
3. Measure Width: Use the 0-30 metric system on the bottom of the main plate. Place the base line on the 90 position, align the subject with the handle ruler, and measure from the bottom of the main plate.
4. Measure Depth: Place the handle ruler in the cavity or align it with the subject.
5. Draw Line: Loosen the screw, adjust the handle ruler to the desired angle, and tighten the screw. You can now draw lines at the correct angle.
The package includes 1 Pcs Angle Protractor Ruler.
