Purpose and function of the lock

The presented lock is dedicated to the rear left side of the vehicle, allowing for precise fitment to the door structure of the first-generation Ford Transit Custom. It is responsible for the mechanical locking of the door leaf, as well as interaction with the handle and control elements inside the door.

Thanks to the proper fitment to the specific location on the vehicle, the lock ensures:

• stable retention of the door in the closed position,
• proper cooperation with the opening mechanism from both the inside and outside,
• appropriate geometry of the catches and latches relative to the bodywork.

Technical characteristics and installation

As a component from the Interior locks and latches category, the rear left door lock is structurally prepared for operation in an intensively used area of the body. Its location in the rear part of the vehicle requires resistance to frequent opening cycles and proper cooperation with door hinges and guides.

This solution is designed for the specific Ford body, which facilitates installation in place of the factory lock. A correctly selected component allows for minimizing the need for door adjustment, as well as maintaining tightness and proper adhesion of the door leaf to the seals.

Condition of the component and service application

The offered lock is a used part, which makes it a practical choice for servicing worn-out or damaged door mechanisms. It is particularly useful in situations where there has been:

• wear of the locking mechanism,
• damage to the lock as a result of a collision or door overload,
• problems with closing or keeping the door in the closed position.

Using an original lock dedicated to the rear left side allows for restoring proper door operation without interfering with the body structure.

Benefits of using a dedicated lock

Selecting the right lock for the Ford Transit Custom Mk1 translates into a number of practical service and utility benefits:

• Compatibility with the factory door system – the lock works with original guides, hinges, and handles.
• Reduction of door play and rattling thanks to the matched latch geometry.
• Possibility of restoring proper closing after bodywork repairs in the rear part of the vehicle.
