Professional windshield installation in accordance with the manufacturer's specifications requires precise adherence to the distances from the edge of the windshield to the bodywork. As bonded windows may only be moved a little after installation, it is advisable to ensure the correct distances during installation. 1.0 mm thick plastic plates on the installation jig allow the glass to be installed with millimeter precision. Simply place the appropriate number of plates in the gap between the windshield and the car body. The gauge can be attached to both the windshield and the car body and can also be used as a gap gauge for the entire car body area (e.g. when fitting fenders, adjusting doors and hoods, etc.).
