Door Hardware Parts
GU New Style 45mm Backset Centre Case Only
Restoring the functionality of your door becomes a much simpler task when you choose the right replacement parts for your existing multipoint locking system. This specific centre case is engineered to work exclusively with the modern range of GU multipoint locks that utilise a 45mm backset measurement. By focusing on replacing only the central gearbox, you save significant time and money while keeping the remainder of your original locking strip securely in place for continued reliable service.
Construction standards for this component reflect the high expectations of modern architectural hardware, as the casing uses materials selected for their longevity and daily mechanical performance. You will find this unit provides a smooth action when lifting the handle to engage the locking points, which maintains the security of your home or premises without requiring a full system overhaul. It represents a sensible, effective choice for maintenance professionals and homeowners who appreciate practical solutions for common locking failures.

Why Choose the GU New Style 45mm Backset Centre Case Only
This component provides a precise match for new style GU locking mechanisms to restore door security efficiently.
Cost Effective Restoration
Replacing the entire multipoint strip is often unnecessary when the fault lies solely within the centre gearbox. This unit allows you to repair the core mechanism of your door lock for a fraction of the cost associated with installing a full system, which keeps your budget managed and your project scope focused on the necessary repair.
Precision Engineering
The unit is designed to meet the exact tolerances required by GU systems to ensure that your handle movement remains fluid and precise. Because it is built for the new style lock series, it integrates perfectly with your existing locking rods and keeps your door operation light and comfortable during daily use throughout the year.
Simple Latch Reversal
You can adjust the orientation of the latch quite easily to suit doors that hang on either the left or the right side. This flexibility simplifies the installation process for tradespeople and homeowners alike, as it eliminates the need to source different handed locks for a project which speeds up your overall repair timeline significantly.
Engineering Quality and Daily Performance
The build quality ensures that your lock handles the mechanical stress of daily locking cycles with ease.
Internal Mechanism Efficiency
The internal cam and spring systems are calibrated to provide a tactile and responsive feel every time you use your lever handle. By using high grade springs and hardened components, the case avoids common issues such as handle droop or stiff operation, which makes your door feel brand new once again after the installation is complete.
Because the force distribution inside the casing is handled by balanced gear teeth, the wear on the spindle is kept to a minimum over many years of service. You will notice that the deadbolt throw and the latch retraction occur with a clean, positive engagement that gives you confidence in the security of your home whenever you lock up for the evening.
Weather Resistance and Durability
The metal housing serves as a protective shell that shields the delicate internal springs and slides from the ingress of dirt or debris that often causes issues in exterior door hardware. It maintains a consistent performance level even when exposed to temperature fluctuations, which means the lock will not become overly stiff or loose as the seasons change throughout the year.
Surface coatings on the latch bolt and deadbolt are chosen for their ability to resist wear and prevent friction during the locking process. These finish details are important because they prevent the metal from galling or sticking inside the strike plate, which helps to keep your door movement quiet and effortless during regular operation for every member of your family.
Installation and Operational Workflow
Follow these steps to ensure a successful swap of your centre case for optimal door performance.
1
Removal of Old Case
Start by removing the door handle sets and the euro profile cylinder from the door leaf, then unscrew the multipoint lock strip from the edge of the door. Slide the strip out of the cavity and remove the screws holding the centre case gearbox to the metal faceplate so you can separate the two parts for a clean exchange.
2
Latch Reversal Adjustment
If you need to change the hand of the latch, push a flat-bladed screwdriver into the small rectangular slot located just above the spindle aperture. Pull the latch outward at the same time to release it from the housing, then flip it over and push it back until it clicks into the correct position for your door orientation.
3
Assembly and Final Testing
Align the new centre case with the locking strip and drive the fixing screws home to secure the gearbox in place. Reinsert the completed strip back into your door, tighten all fixing screws, and verify that the handle lift and key turn work perfectly before you fully close the door and test it under load.
Expert Installation and Care Tip
Check the nightlatch function by removing the latch to expose the small internal screw which you can turn one hundred and eighty degrees for adjustment. Always ensure your door is correctly aligned in the frame before testing the lock to prevent unnecessary strain on the new gearbox during the first few operations.
Technical Specifications
| Feature | Rating / Standard | Practical Details |
|---|---|---|
| Backset | 45mm | This measurement is from the edge of the faceplate to the centre of the handle spindle. |
| Centres | 92mm | The distance between the centre of the spindle and the centre of the euro cylinder. |
| Spindle Type | Split Spindle | Allows the internal and external levers to function independently for added home security. |
| Lock Type | GU New Style | Only compatible with new generation GU multipoint systems for proper fitment. |
Longevity and Trade Reliability
This replacement centre case offers an excellent balance between quality and value for both trade repairs and DIY projects. By choosing this genuine style of replacement, you restore the security of your multipoint lock to the original manufacturer standards for long term peace of mind.
Compatibility and Fitting Notes
This centre case is strictly for new style GU multipoint locks and will not function correctly if you attempt to fit it to old style locking strips.
Verify that your backset measurement is exactly 45mm before purchase because even a small discrepancy can prevent the handle set from aligning with your door holes.
Please contact our technical team if you are uncertain about your specific lock version as there are several subtle differences in the GU range that might affect your choice.
