Stainless Steel 180° Protractor Ruler with Locking Arm

Measure lengths and mark angles with a stainless-steel ruler and 180° protractor combined in one adjustable tool.

Set and mark angles for your project

• ✅ Measure length and angle together – The ruler arm and semicircular protractor support both checks.
• ✅ Hold an angle while marking – The knurled thumb nut locks the arm in the selected position.
• ✅ Read the marked scales directly – Etched graduations provide reference lines for measuring and layout.

Material: stainless steel. Angular scale: 0–180°. Ruler-length options include 10, 14 and 15 cm.
