Product Details

The Standard Tell-Tale Crack Monitor is a precision gauge designed to detect and track crack movement in walls, foundations, and other structures. Whether you're a property owner, structural engineer, or contractor, this device provides reliable data to assess whether a crack is active or stable. How It Works Two overlapping plates work together: A transparent top plate with a fine crosshair cursor. A bottom plate calibrated in millimeters. Simply align the cursor with the grid, and record the X-Y readings. Over time, you can see exactly how much the crack opens, closes, or shifts vertically. Key Advantages High Accuracy – ±1mm tick marks, ±0.5mm discrimination. Wide Range – ±20mm horizontal, ±10mm vertical. All-Weather Use – Suitable for indoor and outdoor applications. Complete Set – Includes screws, installation guide, and crack record sheet. (Adhesive not included.) Peace of Mind Regular monitoring with this tell-tale crack gauge helps you decide when to a professional or simply keep an eye on minor settlement cracks. Durable, reusable, and easy to read.
