Description
The Xpert Glass Thickness Gauge is a professional glass measuring tool for checking the thickness of sealed glass units without removing them from the frame. It is ideal for glazing, window fitting, surveying, maintenance and replacement glass work.
This glass thickness gauge helps installers measure double glazed units while they remain fitted. As a result, it can save time on site and reduce the need to deglaze windows or doors just to confirm sealed unit thickness.
The gauge has a robust steel frame and a double-sided ruler for easy reading from either side. The jaws open up to 104mm, making the tool suitable for measuring around wider frames, deep profiles and larger sealed glass units.
This Glass Thickness Gauge is supplied with a hard moulded protective carry case for safe storage and transport. It is a useful tool for window fitters, glaziers, surveyors, installers, maintenance teams and trade users who need quick and reliable glass thickness measurements.

How to Use a Glass Thickness Gauge
Open the gauge jaws and place them around the glass unit or frame section being measured. Make sure the measuring faces sit squarely against the surfaces for the most accurate result.
Read the measurement from the ruler and record the sealed unit thickness. Use the double-sided ruler from the most convenient angle, especially when working around fitted windows and doors.
After use, wipe the gauge clean and store it in the protective carry case. Avoid dropping the tool or bending the frame, as damage can affect measurement accuracy.
