At first glance, it looks like a ruler, but it’s actually two tools in one: a fixed scale on the body and an extendable measuring arm that can be used to measure both internal and external dimensions, just like a vernier caliper.
Two scales, milled instead of printed
Metric up to 20 cm in millimeter increments; imperial up to 8 inches in sixteenth-inch increments. The graduations are CNC-milled, so they cannot wear off or become illegible. A yellow indicator shows the measurement on the telescoping arm; the textured grip area provides a secure hold for your thumb, and the sliding resistance is adjusted so that the arm stays exactly where you leave it.
- Open the side panels to 15.7 cm for the outer and inner dimensions
- Dual scale: metric up to 20 cm, imperial up to 8 inches
- CNC-milled graduations, permanently legible
- Anodized aluminum in silver and gray, with a yellow indicator
