Unique Design
1.Threaded Non-slip Design
2.Hexagonal Design
The hexagonal plane fits the edge better than the circle, allowing the ruler to be completely perpendicular to the material, making it easier to make more accurate marks.
3.Draws a Parallel Lines
Use with L square ruler increase the marking gauge function, draws perfect Parallel lines while sliding.
4.Draws a Vertical Line
The tall stair gauges can be fixed the L square ruler at the side surface to draws a vertical line.
