Genuine Winkhaus Replacement 35/92 Latch & Deadbolt – Split Spindle Lock Box Centre Case

The Genuine Winkhaus Replacement 35/92 Latch & Deadbolt Split Spindle Lock Box Centre Case is the heart of your multipoint door lock system, responsible for controlling the latch, deadbolt and overall locking performance of your door. Designed specifically for doors operating on a lift lever mechanism, this centre case provides the smooth, positive engagement you expect from a quality Winkhaus multipoint system while restoring worn or failed gearboxes back to factory performance.

Manufactured for use with euro cylinder locks, this lock box incorporates both latch and deadbolt functionality to deliver secure, day-to-day operation and robust night-time security. The precise 35mm backset and 92mm (PZ) centres ensure straightforward compatibility with a wide range of existing Winkhaus door setups, making this an ideal genuine replacement part rather than a full strip replacement. The split spindle design allows independent handle and key operation, a common feature on modern uPVC, composite and timber doors where controlled access and smooth handle action are essential.

With precise fixing measurements of 67mm from the top fixing to the centre fixing and 110mm from the bottom fixing to the centre fixing, along with an overall length of 185mm, this centre case is built to align perfectly with the original Winkhaus rail and keeps your multipoint locking system operating exactly as intended.

Please note: two Winkhaus gearbox rivets are required when fitting this product. These can be found here: IRBOXR

Regular maintenance of your multipoint lock gearbox will significantly extend its lifespan. Applying a specialist lubricant such as GT85 into the moving parts of the gearbox and hooks helps to prevent stiffness, reduce wear and maintain smooth locking action, particularly in high-use doors.

Whilst upgrading your multipoint door lock centre case, it is the perfect opportunity to improve other key components of your door furniture. Replacing your existing Euro cylinder with a high security 3 star cylinder will greatly enhance protection against snapping and forced entry. Similarly, upgrading your door handles at the same time can refresh the appearance of your door while ensuring compatibility with your new single spindle lock case.
