The Wide-body medium-length cab lower bunk assembly is the complete sleeping platform that fits into the cab’s rear area. This Wide-body medium-length cab with lower bunk component is constructed from high‑strength steel tubing and features a durable fabric covering that provides a comfortable resting surface. Its design includes integrated mounting points for the support brackets and fastening hardware, ensuring a stable and rattle‑free installation. The bunk is sized to accommodate the wide‑body cab, offering ample space for drivers to rest during breaks.
The Lower bunk left bracket assembly is the driver‑side support that attaches the bunk to the cab wall. This Wide-body medium-length cab with lower bunk component is fabricated from heavy‑gauge steel and features pre‑drilled holes for easy alignment. It includes captive nuts for simplified installation and is coated to resist corrosion. The bracket’s geometry is designed to distribute the load evenly, preventing sagging over time.
The Lower bunk right bracket assembly is the passenger‑side counterpart, mirroring the left bracket. This Wide-body medium-length cab with lower bunk component ensures balanced support for the bunk, maintaining a level sleeping surface. It shares the same robust construction and corrosion‑resistant finish, guaranteeing long‑term durability. The right bracket is identical in strength and mounting pattern, simplifying installation and parts management.
The Hex bolt is a high‑strength fastener used to secure the brackets and bunk to the cab structure. This Wide-body medium-length cab with lower bunk component is made from alloy steel with a zinc‑plated finish, providing excellent corrosion resistance. Its hexagonal head allows for easy torque application with standard tools, ensuring a secure and vibration‑proof connection. The bolts are supplied in the correct length and thread pitch for the specific mounting points.
The Flat washer is a simple but essential component that distributes the load under the bolt head and nut. This Wide-body medium-length cab with lower bunk component prevents damage to the bracket and cab surfaces, ensuring even clamping force. Made from hardened steel, it resists deformation and provides a smooth bearing surface. Using the correct flat washer is critical for achieving the recommended torque and preventing loosening.
The Left clamp is a securing device that holds the bunk in its folded or stored position. This Wide-body medium-length cab with lower bunk component is spring‑loaded for easy operation and features a rubberised grip to prevent rattling. It is attached to the left side of the cab wall and engages with a corresponding striker on the bunk. The clamp’s robust design ensures that the bunk stays securely stowed when not in use.
The Right clamp (symmetric with left) is the passenger‑side counterpart, identical in function and design. This Wide-body medium-length cab with lower bunk component ensures that both sides of the bunk are securely retained when stowed. Its mirror‑image construction allows for a balanced appearance and consistent operation. The clamp is easy to release and engage, making it convenient for daily use.
The Open type oval head blind rivet is a permanent fastener used to attach the clamps and other trim pieces. This Wide-body medium-length cab with lower bunk component is installed from one side, making it ideal for blind applications. Its oval head provides a low‑profile finish, and the rivet’s aluminium body ensures corrosion resistance. The rivet is supplied in the correct size for the specific mounting holes, providing a secure and vibration‑resistant joint.
The Left support tube for bunk is a rigid steel tube that provides additional structural support for the left side of the bunk. This Wide-body medium-length cab with lower bunk component is installed between the bracket and the cab floor, reducing flex and enhancing stability. Its tubular shape offers high strength‑to‑weight ratio, and the ends are fitted with rubber isolators to dampen vibration. The support tube is powder‑coated for durability.
The Right support tube for bunk (symmetric with left) is the corresponding tube for the passenger side. This Wide-body medium-length cab with lower bunk component ensures balanced support across the entire bunk width. It is identical in construction and finish, providing the same level of rigidity and vibration isolation. The right and left tubes work together to distribute the load evenly, preventing any twist or sag.
The Spacer tube is a cylindrical component that maintains correct spacing between the bunk and the cab wall. This Wide-body medium-length cab with lower bunk component ensures that the bunk is positioned at the correct height and angle for comfortable sleeping. It is precision‑cut to exact lengths and made from aluminium to reduce weight. The spacer tube also acts as a protective buffer, preventing metal‑to‑metal contact and subsequent corrosion.
The Cross recessed pan head screw is a versatile fastener used for attaching trim pieces and clamps. This Wide-body medium-length cab with lower bunk component features a large pan head that provides a wide bearing surface, preventing pull‑through. The cross recess allows for easy driving with a standard screwdriver, and the screw is made from stainless steel for corrosion resistance. It is supplied in the correct length for each specific application.
The Blind rivet nut M8 is a threaded insert that provides a strong anchor point in thin sheet metal. This Wide-body medium-length cab with lower bunk component is installed from one side, making it ideal for blind mounting. It features a M8 thread and is made from carbon steel with a zinc finish, offering excellent pull‑out resistance. The rivet nut is used to secure the support tubes and other components, ensuring a reliable and durable connection.
