The York Survey 37005 is a highly reliable structural monitoring tool designed to track wall movement over extended periods. Featuring a simple yet effective overlapping two-plate design, it monitors the opening, closing, and vertical shear movement of structural cracks. Engineered with a high-precision, silk-screened grid and a vibrant red crosshair, it enables users to observe minimal shifts down to a fraction of a millimetre. Essential for building control, diagnostic site surveys, and general property maintenance.

• High-Precision Engineering - Features a crisp, silk-screened grid with both positive and negative graduations marked.
• Ultra-Fine Red Crosshair - Allows surveyors to easily view and accurately estimate shifts as small as 0.25mm.
• Dual-Axis Tracking - Monitors structural changes simultaneously across horizontal opening/closing and vertical shear planes.
• Complete Recording Set - Supplied with official crack recording sheets to efficiently log and track data points over weeks and months.
• Simple Installation - Can be quickly fixed across the fault line using standard structural adhesive, or secured mechanically with screws and wall plugs.
