Precision Protractor


"Why it should have taken from the time of the construction of the pyramids until 1996 for someone to think of this, I don't know, but at one stroke the inventors of this device have eliminated parallax error."
Jerry Adler, Senior Editor, Newsweek

  • This 21st century Marking Protractor has micro-fine guide holes at every 45°, 30°, 22.5°, 5°, 1° and 0.5° interval to plot any angle with ease and absolute accuracy.
  • Metal T-Bar and see-through crosshairs provide exact alignment against the edge of your workpiece.
  • Remove the T-Bar to work on flat surfaces or to use the 6" centering scale.
  • FOUR angle scales: 0° left to 180° right, 180° left to 0° right, 0° top to 90° left and right, and 90° top to 0° left and right suite every need.
  • Easy on the eyes, incredibly accurate, and fun to use!
