Purpose and function of the striker

The lock striker mounted on the rear right door is responsible for mechanically locking the wing after closing, ensuring the door is pulled stably against the body frame. A properly selected component reduces unwanted play, minimizes vibrations while driving, and supports the tightness of the rear structure, which is important for both cargo protection and acoustic comfort.

Using a striker structurally matched to a specific Citroën model allows for maintaining the factory closing geometry, thanks to which the mechanism works smoothly and the door does not require excessive force to close.

Construction and fit for Citroën Relay III

The presented striker has been designed to work with the factory lock of the rear right wing in the third-generation Relay model. The shape, spacing of mounting points, and the profile of the working surface are adapted to the original door construction, which facilitates installation in place of a worn or damaged component.

Such a fit translates into:

• stable guidance of the wing when opening and closing,
• repeatable door positioning relative to seals and the body,
• reduced risk of accelerated wear of hinges and the lock.

Condition of the component and benefits of using a used part

The striker comes from the secondary market, which means it is a used part that retains the functionality required for further operation. For the user, this means the possibility of an economical repair of the rear body zone while maintaining compliance with the vehicle's original design.

Using a verified used component allows you to:

• lower the cost of restoring the full efficiency of the lock mechanism,
• maintain the factory design solution without the need for modifications,
• maintain operational consistency with other door components.

The importance of the correct striker in vehicle operation

In commercial vehicles, the rear doors are heavily used, and the lock striker works with every opening and closing cycle. Wear or deformation of this element can lead to closing problems, the formation of play, and in extreme cases, to the uncontrolled opening of the wing. Replacing it with a properly selected striker restores the correct cooperation of the lock with the body and increases the safety of the transported cargo.

If you are planning a comprehensive repair or modernization of the door closing zone in your Citroën and need other elements from the same group, such as catches, inserts, or locking mechanisms, check the available parts in the Citroen Locks and Latches category.

Additional information and technical advice

When selecting a striker for the rear right wing, it is worth paying attention to compatibility with the body generation and door configuration (asymmetric wings, opening method). Installation in conditions allowing for precise adjustment of the position relative to the lock is recommended, so that after closing the door, the body lines remain even and the seals work under proper pressure.
