01AUTOMOTIVE REPAIR & SPECIALITY TOOLS
Precision tools for watching walls breathe
A quiet set of twelve clear panels, ready to be placed against the plaster where a line has begun to form. They sit flush against the surface, turning an invisible shift into a visible record.
These acrylic gauges allow you to track the evolution of cracks on flat walls over time. They suit homeowners and inspectors who need a simple, manual method for observing structural changes without complex equipment.


02MATERIALS
Transparent acrylic for clarity
Each monitor is crafted from high-quality acrylic, chosen for its strength and smooth finish. The material resists wear and remains difficult to break during handling. Its transparency ensures that the underlying crack remains fully visible through the panel, providing an unobstructed view of the fracture line as it develops.

04APPLICATION
Tracking movement on flat surfaces
Designed specifically for flat walls, these tools help document how a crack evolves. By placing the monitor over the fissure, you can observe any lateral or vertical displacement. It serves as a practical instrument for telling the story of structural change, capturing the narrative of a building's slight adjustments over months or years.
