Plumber’s Folding Rule
When working with 45 degree elbows, this rule eliminates figuring and chance of error. It is graduated on one side, in black, consecutive
inches to 1/16, both edges. Other side in red, 45 degree scale inches to 1/16, upper edge only. Turning rule from black to red gives, at a direct reading, the corresponding 45 degree elbow measurement.
