Rose Sheoak 2" 45 Degree Marker
Colen Clenton recalibratable squares and markers are very unique because if they are knocked out of square they can be recalibrated back to square. The adjacent photo shows the quality of workmanship and engineering involved with making these squares recalibratable which ensures you have a lifetime tool. Readjustment is easy and instructions come with the tool showing how it is done.
The size of the marker is measured from the inside of the handle to the tip of the blade.
