Genuine Roto H600 Multipoint Door Lock Replacement
When your main entrance door begins to stick, or the handle feels stiff when you lift it, the central locking mechanism is usually showing signs of wear. The Roto H600 92mm Centres 35mm Backset 2 Hook Multipoint Lock offers an exact, dependable solution for domestic and commercial exterior doors fitted with classic Roto hardware. Designed specifically to restore smooth operation and solid weather protection, this high-grade mechanism ensures your entrance remains properly sealed against external elements and unwelcome intruders alike.
Modern residential doors depend on robust multilever locking systems to hold the door leaf securely against the frame. Over time, continuous use, seasonal shifting, and changing temperatures can put excessive strain on older gearboxes and moving parts. Replacing your tired hardware with this genuine Roto unit guarantees precise alignment, restoring the original balance and reassuring clunk of a properly shut door. At Doorfit, we understand that finding the right hardware replacement can feel daunting, which is why we supply accurate, trade-tested locking systems that make repairs straightforward.
Featuring an industry standard 92mm PZ dimension, a practical 35mm backset, and two solid hook bolts separated across a generous 1490mm span, this hardware unit delivers exceptional clamping pressure along the entire vertical edge of your door sash.

Dual Hook Security
The primary line of physical defence on this lock comes from two tapered, heavy duty steel hooks. Positioned 1490mm apart, these hooks extend deep into the frame keeps when you lift the door handle. Their curved shape pulls the door leaf firmly inward, preventing physical separation and stopping intruders using jemmy bars or leverage tools to force the door out of its rebate.
Because the hooks pull the door snugly into the weather seals, they also eliminate chilly draughts, rattling sounds during high winds, and moisture ingress. You gain both reliable physical protection and enhanced thermal efficiency throughout the colder months.
Universal Handing
Door handing can often cause confusion when purchasing replacement hardware. The central latch on this mechanism is completely reversible, allowing you to fit it onto doors that open inwards or outwards, hanging on either the left or the right side of the opening.
Reversing the latch requires only basic hand tools and takes less than a minute. By removing the small retaining screw on the rear of the latch casing, you can pull the latch out, turn it through 180 degrees, and slide it back into position, ensuring a simple fit on site without delays.
Understanding Key Dimensions and Sizing
Multipoint locks are precision engineered components, which means accurate measurements are essential before you begin your replacement project. Getting the measurements right ensures that the new strip drops into the existing door prep without requiring extensive carpentry or routing work.
The PZ measurement refers to the distance from the centre of the spindle hole, which drives the door handle, down to the centre of the circular section of the euro cylinder keyway. On this model, that distance is 92mm, which represents the most widespread handle standard across the UK. You can pair this mechanism with nearly all standard 92mm lever furniture available today.
The backset measurement is the distance from the flat outer surface of the metal faceplate to the centre line of the spindle hole. This version features a 35mm backset, which is widely found on residential uPVC and composite door sections. A 35mm depth provides comfortable clearance for your hand while keeping the internal lock components safely enclosed within standard door profile chambers.
Finally, verify the distance between the two locking hooks. Measuring between the centres of the top and bottom hooks yields 1490mm. Checking this measurement against your existing door frame keeps confirms whether the new hooks will engage directly into your current receivers.

Step by Step Installation Advice
Swapping out an old mechanism for this unit is a straightforward job for experienced DIY enthusiasts and professional tradespeople alike. Following sensible steps ensures that the installation runs smoothly and your new lock performs properly for years to come.
- Remove the handle set and cylinder. Unscrew the interior handle fixing bolts, remove the lever furniture, and take out the cylinder retaining screw on the edge of the door to slide out the euro cylinder.
- Extract the existing strip. Remove the fixing screws positioned along the full length of the outer metal faceplate. Carefully pull the entire multi point mechanism outward from the edge rebate.
- Check your handed latch. Compare the orientation of the latch bolt on the new Roto H600 92mm Centres 35mm Backset 2 Hook Multipoint Lock with the door frame strike plate. If necessary, loosen the rear screw, turn the latch around, and resecure it.
- Slot in the new mechanism. Slide the new faceplate into the existing rebate channel. Line up the screw holes and loosely start the fixings by hand before tightening them down evenly with a manual screwdriver.
- Reassemble the cylinder and furniture. Reinstall the euro cylinder and test it with the door standing open. Refit the handles, then lift the lever to confirm the hooks and deadbolt move smoothly without resistance.
- Final closure test. Close the door gently against the frame. Lift the handle and turn the key. If you feel any stiffness, fine tune your frame keep plates slightly so the hooks engage cleanly without binding.
Helpful Maintenance Tip
Never apply thick grease, motor oil, or standard WD40 to multipoint lock gearboxes and sliding tracks. These lubricants tend to attract airborne dust and road grit, which turns into a grinding paste that wears down internal gears. Instead, apply a dedicated light silicone spray or dry PTFE lubricant once or twice a year to maintain effortless, reliable movement.
