Purpose and function in the vehicle

The presented Mercedes-Benz CLC CL203 Boot Tailgate Hook Lock Latch Catch Rear is designed specifically for the rear body section of the Mercedes-Benz CLC CL203 model. It is responsible for the mechanical locking of the trunk lid, working in conjunction with hinges, actuators, and the opening system. Its placement in the rear area of the vehicle allows for the direct transfer of closing and opening forces, which translates into stable retention of the tailgate in the closed position while driving.

Thanks to a design consistent with factory solutions, this component maintains the correct latch geometry, which reduces the risk of play, rattling, or closing issues. This is particularly important in daily use, when the tailgate is frequently opened and closed.

Benefits of using an original tailgate lock

Using an original lock in the tailgate brings a number of practical technical benefits:

• preservation of the factory operation of the locking mechanism,
• proper fit to body mounts without modifications,
• consistent cooperation with other elements of the opening and closing system,
• reduced risk of leaks resulting from improper tailgate closure.

For the user, this means more predictable tailgate operation, no need for makeshift adjustments, and maintenance of trunk usability at a level close to factory solutions. The Loading Tailgates category includes exactly these types of components responsible for the safe and stable closing of the luggage compartment.

Assembly and operational characteristics

The offered Mercedes-Benz CLC CL203 Boot Tailgate Hook Lock Latch Catch Rear is intended for installation in the rear of the vehicle, in place of the factory latch. The design, intended for a specific Mercedes model line, allows for installation in existing mounting points without the need to interfere with the body structure. This facilitates service work and shortens the time required to replace a damaged or worn component.

As a part sourced from a used vehicle, the lock retains its original geometry and operation, which helps maintain proper pressure of the tailgate against the seals. In practice, this translates into limiting the ingress of water and contaminants into the luggage compartment, provided that other system components are in good condition.

Use in service and repairs

This type of component is particularly useful in situations where there are problems with closing the tailgate, it opening accidentally, or it not being held stably in the closed position. Replacing the lock with an original component allows for restoring the proper operation of the mechanism without the need to modify the vehicle's installation.

In workshops specializing in the Mercedes brand, this type of solution is often chosen as a way to restore the functionality of the rear body section while maintaining compliance with factory assembly standards.
