Crack Monitor with 2 Pre-Set Pegs, Tell-Tale Wall Deformation Measurement & Recording Tool(5PCS)

This professional-grade crack monitoring kit offers precise, reliable measurement of wall deformations over time. Featuring two overlapping plates—a calibrated bottom plate with millimeter markings and a transparent top plate with a crosshair cursor—it ensures ±1 mm accuracy (±0.5 mm discrimination) for tracking horizontal (±20 mm) and vertical (±10 mm) movements. The redesigned polymer fixing columns simplify installation without glue, while the included screws, adhesive, instructions, and crack record sheets provide a complete solution. Ideal for structural monitoring, its durable design and clear measurement grid deliver long-term performance. Perfect for contractors, engineers, or homeowners concerned about structural integrity.
