The Cross flute screw is a high‑quality fastener with a cross‑recessed head, designed for secure attachment of the cover plate and trim components to the Roof window cover device. Manufactured from zinc‑plated steel, it offers excellent corrosion resistance and a secure, vibration‑proof connection. Its precise threading ensures easy installation with standard screwdrivers, reducing assembly time and ensuring that all panels remain firmly in place under vibration.
The Washer is a large‑diameter flat washer that distributes clamping load evenly under the screw heads. Manufactured from steel with a protective zinc coating, it prevents damage to the mounting surfaces and ensures a secure, rattle‑free connection. Its wide surface area is essential for maintaining proper torque and load distribution, especially when securing the plate welding assembly and trim panels to the cab roof. This washer is a critical hardware component of the Roof window cover device, ensuring long‑term reliability.
The Switch device assembly is the control mechanism that allows the driver to open, close, or tilt the roof window cover. It features a durable actuator and integrated locking system that provides positive engagement and smooth operation. Manufactured from high‑strength materials with a corrosion‑resistant finish, this assembly is designed to withstand repeated use and maintain its precise operation over the vehicle’s lifetime. The switch device is ergonomically positioned for easy access, enhancing driver convenience and control.
The Plate covering is the interior trim panel that conceals the roof window mechanism and provides a finished appearance to the cab headliner. Manufactured from durable plastic with a textured finish, it matches the cab interior and offers a clean, professional look. The covering is designed to fit precisely over the plate welding assembly, with cutouts for the switch and hinges. Its lightweight construction and easy‑to‑clean surface make it a practical addition to the Roof window cover device, enhancing both aesthetics and functionality.
The Rivet 6 is a permanent fastener used to secure the hinge brackets and other components to the plate welding assembly. Manufactured from high‑strength steel with a corrosion‑resistant coating, it provides a durable, vibration‑proof connection that cannot loosen over time. Its low‑profile head ensures a flush finish, and its installation is quick and reliable using standard riveting tools. This rivet is an essential fastening element for the structural integrity of the Roof window cover device.
The Hinge is a precision‑engineered pivot mechanism that allows the roof window cover to open and close smoothly. Manufactured from corrosion‑resistant steel, it provides a durable and quiet operation that withstands repeated use. The hinge is designed for easy installation and is a critical component for the functionality of the Roof window cover device, ensuring that the cover moves freely and stays securely in position when closed.
The Seal strip is a high‑quality rubber gasket that provides a watertight and airtight seal between the roof window cover and the cab roof. Manufactured from durable EPDM rubber, it resists UV degradation, ozone, and extreme temperatures, ensuring long‑lasting sealing performance. This strip prevents water, dust, and wind noise from entering the cab, maintaining a quiet and comfortable environment for the driver. Its precise fitment ensures that the cover remains securely sealed, preventing any rattling or loosening over time. The use of high‑quality materials guarantees durability and long‑lasting performance, even under harsh operating conditions. This seal strip is an essential component of the Roof window cover device, providing the primary weather seal for the roof window.
