LEVELPEGS are used to pour self-leveling compounds and mortar to a specific, accurate depth. The new LEVELPEG design features dual measurement indicator marks in inches and millimeters: Side one measures between 6 to 64 millimeters and side two measures between 3/16 to 2 1/2 inches. When used in conjunction with the NIVCOMP, you simply read the proper height on the NIVCOMP then cut the LEVELPEG to match.
