Corner Crack — Acrylic Crack Gauge for clear, durable crack monitoring Key benefits Track crack progression reliably: a simple, analog way to monitor horizontal or vertical movement so you can detect change and document development over time. High visibility and accuracy: a high-clarity acrylic plate with a readable measurement grid makes it easy to read small displacements and record results. Durable and long-lasting: made from high-quality acrylic that is smooth, wear-resistant and difficult to break, so the gauge stays usable on sites and in the field. Main features Material: high-quality, transparent acrylic for clear viewing of the crack and measurement markings. Readable measurement grid: printed grid lets you observe and record movement precisely without electronic tools. Analog, low-complexity instrument: simple to use on site for routine checks and longer-term monitoring. Designed for horizontal or vertical measurement: intended to measure crack movement in a single plane, including corner and linear cracks. How it solves problems Eliminates guesswork: the transparent plate and grid make it easy to compare the crack position over time, helping you decide when repairs are needed. Reduces repeat visits and saves time: quick visual checks allow efficient on-site assessments and straightforward documentation of changes. Suited to field conditions: the wear-resistant acrylic withstands handling and repeated readings. Practical use scenarios Homeowner or building inspector monitoring a wall crack: place the gauge across the crack to record movement between inspections and provide clear evidence for repair decisions. Contractor assessing corner cracks: use the gauge to monitor horizontal or vertical displacement near openings, corners or junctions during repair work. Conservation or renovation projects: track how cracks in plaster, masonry or finishes develop over time to inform restoration strategy. What to expect A robust, clear acrylic gauge designed for straightforward, repeatable measurements of crack displacement in a plane. No complex setup — use the measurement grid to visually track changes and log the results for comparison. Corner Crack is a practical, precision analog instrument for anyone who needs a simple, durable solution to monitor and document crack development in walls and similar surfaces.
