Tru-Contour has developed an easier and more accurate way to set your mandrels and hole formers at the desired degree on 4' and 5' manholes. The new Protractor is constructed of .25" high density polyethylene making it lightweight yet durable. The provided handles make it easy to set the protractor into place.

Once the Protractor is set, it is a simple process to locate the desired degree of angle to place your hole former or mandrel. The Protractor provides exact measuring, erasing the inaccuracy of using a tape measure to find the angle. There's no doubt the new Tru-Contour Protractor will save time, money, and effort!
