The D Half 6 Inch Protractor is a practical middle-size geometry tool for students who want a clearer arc than a tiny pocket protractor without carrying an oversized drafting piece. Its six-inch width works well for everyday notebook constructions, worksheets and project diagrams.

The semicircular edge is graduated from 0 to 180 degrees. Number rows begin from opposite ends, so the correct zero can be selected whether an angle opens to the left or the right. A central 90-degree reference helps identify right angles at a glance.

Because the body is transparent, the vertex and both rays of a drawn angle remain visible during placement. Align the centre mark with the vertex, rest the straight baseline on the first ray and read where the second ray crosses the curved scale.

Each Rs. 75 order contains one 6-inch D Half protractor. This is the balanced middle option in the Safencia range: larger than the separate 4-inch model, yet more compact than the 8-inch and 10-inch versions. Select the size that best matches the drawings and desk space you normally use.
