BEZEL-POWER WINDOW(AST)

A window (glass) is the transparent panel in the cab that gives the driver visibility while keeping out weather and noise.

Fixed or moving in its frame, it provides a clear, safe view; windshields are laminated so they hold together if damaged.

Windows are fitted in the windshield, doors, and rear of the cab. The correct glass matches the opening and safety standard, and a damaged windshield should be replaced promptly for safe vision.
