Multipoint Lock Repair
GU New Style 35mm Backset Centre Case Only
Homeowners often encounter the frustration of a stiff or unresponsive door lock when the internal mechanism finally succumbs to years of mechanical wear and tear. This GU new style centre case provides a focused solution for property owners who need to restore security without replacing the entire multipoint system embedded within the door profile. It is specifically engineered to replace the internal gearbox of your existing hardware, which helps you avoid the significant labour costs and potential joinery damage associated with a complete multipoint lock removal.
Crafted to meet the high standards expected for residential entrance doors, this unit handles the daily stresses of repeated opening and closing cycles with consistent performance. The casing is finished to resist corrosion from the humid British climate, while the internal gear train is precision machined to deliver a firm feel through the lever handle. By focusing on the central component, you ensure that your door hardware remains functional and secure for many years to come.

Why Choose the GU New Style 35mm Backset Centre Case Only
This hardware provides a precise repair path for maintaining secure entry points without unnecessary component waste.
Targeted Mechanical Repair
You can address specific locking issues by replacing only the faulty gearbox rather than the full strip. This approach saves time on site and keeps the existing shoot bolt and roller systems perfectly aligned, which preserves the original factory fit and setup of your composite or timber door frame.
Consistent Lever Action
The internal spring cassette is factory tensioned to support your handle set, so you will notice an immediate improvement in how the lever feels during operation. Because the deadbolt throw is calibrated for exact alignment with your frame keeps, every lock cycle provides a secure feel that reassures your household.
Adaptable Handing Configuration
The latch reversal system allows for quick adjustments so that the lock suits both left and right handed door configurations. You can move the latch tongue easily with simple hand tools, which gives you complete flexibility when managing inventory or performing urgent repairs for different types of door styles.
Engineering Quality and Daily Performance
Precision manufacturing and high-grade materials define this centre case to support reliable long-term security.
Internal Mechanism and Force Distribution
The internal gears are hardened to survive the repetitive strain of daily use, which means the mechanism remains responsive even after thousands of locking cycles. Every tooth within the gear train is machined to minimise friction, so the handle action remains light and smooth throughout the life of the product.
The central spindle hub is designed for split spindle operation, which maintains a high level of security by requiring a key for external entry while allowing for convenient exit. This distribution of mechanical force across the gear teeth ensures that the handle does not become loose over time and the deadbolt retains its structural integrity.
Weather Resistance and Long-Term Finish
External doors are exposed to fluctuating temperatures and moisture, so the outer casing of this gearbox is treated to prevent the common effects of oxidation. This finish protects the delicate internal components from dampness, which helps to keep the springs and moving parts free from the typical grime that leads to failure.
By preventing corrosion within the gear housing, the lock continues to function correctly during winter months when hardware is often subjected to the most intense pressure. You gain peace of mind knowing that the core of your security system is protected against the elements that usually compromise standard door furniture over the long term.
Installation and Operational Workflow
Follow this professional approach to swap the gearbox while maintaining the integrity of the door profile.
1
Secure the Door
Open the door and remove the handle set along with the cylinder, as these parts must be clear of the centre case to allow for removal. You should then unscrew the fixing points along the faceplate which hold the multipoint strip to the edge of the door, allowing the whole strip to be withdrawn carefully.
2
Extract the Case
Once the strip is flat on a secure surface, unscrew the gearbox from the faceplate to separate it from the shoot bolts. It is helpful to take a quick photo of the internal linkage orientation before you detach the old case, so you can reconnect the drive rods accurately during the final assembly stage.
3
Reassemble and Test
Slide the new centre case into position on the drive strip and tighten the fixings firmly, ensuring that the rods move back and forth without catching on the casing. You should test the latch and deadbolt movement before you re-attach the strip to the door to guarantee that the operation is completely smooth.
Expert Installation and Care Tip
Use a light application of silicone lubricant on the moving parts of the gearbox before reinstallation to ensure the components operate with minimal resistance. Verify that your handle set fits the split spindle perfectly so the leverage remains consistent and does not stress the internal gears.
Technical Specifications
| Feature | Rating / Standard | Practical Details |
|---|---|---|
| Backset | 35mm | Measure from the faceplate edge to the centre of the handle spindle to confirm this is correct. |
| PZ Centres | 92mm | The distance from the centre of the spindle to the centre of the euro cylinder hole. |
| Operation | Split Spindle | Designed to allow key access from outside while remaining secure at all times. |
| Handing | Reversible | Use a screwdriver to push the latch out and rotate it for left or right opening doors. |
Longevity and Trade Reliability
This replacement gearbox is manufactured to match original standards, which provides a high degree of confidence for both homeowners and professional installers. By investing in a high quality centre case, you extend the functional life of your locking system for many years while avoiding the waste of a total system replacement.
Compatibility and Fitting Notes
Check the existing GU multipoint system to ensure it matches the new style configuration before you attempt the installation.
Maintain the existing drive rods and rollers as they remain compatible with this gearbox as long as the linkage points align correctly.
Test the locking action with the door in the open position to ensure that every throw point clears the frame stops without catching.
