Common Use Case or Symptoms:

Use when the main cab door pane is cracked - a grader door gets opened and closed dozens of times a shift, and once the glass is starred the vibration of the machine will finish it.

⚠ Please Inspect Glass Upon Arrival: Glass items may experience breakage during transit. Before signing the Bill of Lading, thoroughly inspect all glass shipped via LTL Truck Freight. If delivered by UPS and found broken, contact us within 48 hours of delivery. Your prompt inspection is crucial for a smooth claims process.
