The Curv-O-Mark Universal Level (#33) is a must have multipurpose tool. Featuring a 360-degree adjustable protractor dial bubble (DSL,) the level has two cast-in 25-pound magnets to securely hold the unit in place on any steel surface including the underside of a pipe or beam. This permits hands free leveling, even in the tight spots. The bubble is mounted on a protractor dial, so it can be used in any position and still maintain accurate readings. Both faces of the level have deep, cast-in grooves for self-centering on the contour of the pipe and because the magnets are cast-in, they won’t interfere with the use of the level on nonmagnetic materials.  For aligning pipe flanges (two holing,) the universal level comes with a two threaded, self-aligning conical spacer and conical nut and bolt units.
