This rear window panel is a direct-fit replacement for the cab bodywork of the host tractor. It is a glazed assembly that seals the rear opening of the cab, providing visibility to the rear while maintaining the structural enclosure of the operator station. The panel is mounted into the cab frame using the original hinge and latch hardware. A cracked or broken window compromises the cab's weather seal and structural integrity, allowing dust and moisture ingress. The manufacturer produces this component to match the original curvature and mounting points, so no modification to the cab frame is required for installation.
