General Ultra Rule Protractor (1 Each)

The Ultra Rule precision protractor has micro-fine guide holes at every 45 Degrees, 30 Degrees, 22.5 Degrees, 1 Degrees and 0.5 Degrees intervals to plot any angle with ease and absolute accuracy. A metal T-bar and see through cross hairs 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 Degrees left to 180 Degrees right; 180 Degrees left to 0 Degrees right; 0 Degrees top to 90 Degrees left and right, and 90 Degrees top to 0 Degrees left and right.
