Winkhaus Scorpion Gearbox for Multipoint Door Lock 35mm Backset 92 PZ

Winkhaus Scorpion Gearbox Multipoint Split Spindle Door Lock Centre Case 92PZ - 35mm Backset

The market's most compact multipoint lock gearbox with unmatched versatility for uPVC and composite door lock replacements

Winkhaus Scorpion Gearbox represents the pinnacle of German engineering in multipoint door lock systems. Measuring just 185mm in height, this is the smallest gearbox on the market, making it the ideal replacement for Winkhaus Scorpion multipoint locks on uPVC doors, composite doors, and timber doors. The split spindle operation offers exceptional flexibility, allowing you to configure this single lock mechanism for both split spindle and lever-operated applications without purchasing separate units.

Manufactured by Winkhaus, a trusted name in European door hardware and security products, this genuine gearbox features their distinctive rivet-fixing system that simplifies replacement and maintenance. The robust latch and hookbolt configuration delivers reliable door security for modern homes, whilst the non-handed design eliminates confusion during installation and ensures you always have the right part for the job.

Key Benefits:

• Dual Operation Versatility – The split spindle design works as both a split spindle and lift lever operation. Simply insert a solid 8mm spindle all the way through the follower to convert to lever operation, giving you two locks in one without any price premium. Perfect for door handle replacement projects where operation type needs to be flexible.
• Rapid Identification System – Winkhaus colour-codes their door locks with side stickers: green denotes split spindle operation, making identification instant on-site. No more guessing or measuring countless specifications to identify the correct replacement gearbox for your multipoint lock system.
• Rivet Fixing – The unique rivet attachment system (rather than screws) makes Winkhaus gearboxes instantly recognizable and remarkably simple to swap. Remove the pins with a punch, replace the gearbox, and reuse the original rivets for a secure, lasting installation.
• Universal Non-Handed Design – Forget about left or right-handed locks. This non-handed gearbox installs on any door, eliminating ordering errors and reducing your stock requirements for uPVC door repairs and composite door maintenance.
• Latch & Hookbolt Security – The combined latch and hookbolt mechanism in the main gearbox provides superior door security compared to latch-only systems. The hookbolt engages into the frame, resisting forced entry attempts whilst the latch ensures smooth everyday operation of your door handle.
• Quick Latch Reversal – Need to reverse the latch direction during installation? Simply push in the latch to reveal a screw in the back of the lockcase. Undo, reverse, and replace – job done in seconds without requiring specialist knowledge for your door lock repair.
• Genuine Winkhaus Quality – This is a genuine Winkhaus product, not a pattern copy. You receive the precision engineering, quality materials, and reliability that have made Winkhaus Germany's most respected lock manufacturer for uPVC and composite door security.

Pro Tips:

Pro Tip: The split spindle version offers superior flexibility for door lock replacement jobs. Even if your current lock is lift lever operated, choosing the split spindle allows you to keep one type in stock that handles both configurations. Insert a solid spindle through the follower for lever operation, or use a split spindle for independent inside/outside door handle operation. There's no price difference, so always opt for the split spindle for maximum versatility. Additionally, Winkhaus gearboxes feature a groove above the spindle specifically designed to accommodate door handles with a screw above the lever – a thoughtful detail that simplifies installation with certain handle ranges for uPVC and composite doors.

Frequently Asked Questions:

How do I know if this gearbox will fit my uPVC or composite door?

Winkhaus gearboxes are among the easiest to identify due to their distinctive rivet fixing system. Check the side of your existing gearbox for rivets (one top, one bottom) rather than screws – this confirms it's a Winkhaus multipoint lock. The green sticker on the side indicates split spindle operation. Measure your current lock's backset (35mm in this case) and PZ centres (92mm) to confirm compatibility. The 185mm case height makes this the smallest gearbox available, so if your current lock is Winkhaus, this will fit your door. For assistance with identification, we stock a comprehensive range of Winkhaus products and can help you match your existing door lock.

Can I use this split spindle lock if I currently have a lift lever lock?

Absolutely. The split spindle design is actually more versatile than a lift lever for door lock replacements. To use it as a lift lever lock, simply insert a solid 8mm square spindle all the way through the follower – it functions identically to a dedicated lift lever lock. This is why we primarily stock split spindle versions: they offer two locks in one with no price difference. You gain the option of independent inside/outside handle operation (split spindle) or simultaneous operation (lift lever) depending on your spindle choice.

What's the difference between this genuine Winkhaus gearbox and cheaper pattern copies?

Genuine Winkhaus gearboxes are manufactured in Germany to exacting standards with premium materials for superior door security. Pattern copies often use inferior metals that wear quickly, plastic components that crack under stress, and imprecise tolerances that cause binding and unreliable operation. Winkhaus locks are engineered to operate smoothly for decades with minimal maintenance. The rivet system, latch reversal mechanism, and hookbolt engagement are all designed with longevity in mind. When your door security depends on the lock functioning perfectly every time, genuine Winkhaus is the only sensible choice for your multipoint lock replacement.

How difficult is it to replace a Winkhaus gearbox on my door?

Winkhaus gearboxes are among the simplest to replace, even for DIY enthusiasts tackling their first door lock repair. The rivet system requires only a punch to remove – knock out the top and bottom pins on the side of the case, remove the old gearbox, insert the new one, and tap the original rivets back into place. No screws to align, no threading issues, just straightforward mechanical assembly. The latch reversal is equally simple: push in the latch to reveal the screw, undo it, reverse the latch, and replace the screw. Most multipoint lock replacements take 15-20 minutes.

Will this work with my existing door handles and euro cylinder?

Yes, this gearbox accepts standard 8mm square spindles (both split and solid) and standard euro profile cylinders, making it compatible with the vast majority of uPVC and composite door handles and locks. The non-handed design means you don't need to worry about door orientation. The groove above the spindle accommodates door handles with a screw above the lever, expanding your handle options. Simply ensure your handles are designed for 92mm PZ centres and your cylinder is sized appropriately for your door thickness. We stock a comprehensive range of compatible Winkhaus handles, keeps, spindles, and accessories to complete your door lock installation.
