Multipoint locks span the entire height of a door’s edge and provide exceptional security by engaging multiple locking points - such as hooks, rollers, deadbolts, or pins. These mechanisms distribute the load of forced entry attempts more effectively than traditional single-point or mortice locks. Modern multipoint locks are commonly found on UPVC, composite, and timber doors, offering benefits that include better draught proofing, enhanced security, and greater convenience.

At Duffells, we supply a vast array of multi-point locks compatible with various door materials and configurations. Whether you need a replacement multipoint lock for a front door, a nightlatch locking variant for enhanced convenience, or a double-spindle system for added external security, our trade-only approach guarantees you gain access to specialised knowledge and rapid dispatch. For over six decades, we have supported installers, locksmiths, and contractors with premium locks, cylinders, and door hardware - helping them complete jobs on time and to the highest standard.

A multi-point locking system consists of a central mechanism (the gearbox) and a series of additional locking points arranged vertically along the door’s faceplate. These additional locking points increase security at multiple points, typically near the top, centre, and bottom of the door edge. Depending on the model, those points may be hooks, rollers, deadbolts, or a combination, all controlled via the same central gearbox.

Multipoint locks can be activated in different ways, often by lifting the handle or turning the key, each locking point engages simultaneously, securing the door more effectively than a single-point system. These locks are commonly used on UPVC, composite, and timber doors. Many insurance companies and homeowners prefer multi-point locks for exterior doors because of their superior anti-intrusion performance.

The faceplate is the long metal strip running vertically along the door edge. Its width and style can differ:

• Flat Faceplate: Common on many UPVC door profiles.
• Rounded/Radius Ends: Sometimes found on specific composite or timber configurations.
• U-Track Faceplate: A channel-shaped design that fits into particular door profiles.

Several types of locking points can be spaced out along the faceplate:

• Hooks: Offer excellent anti-separation strength.
• Rollers: Improve weather sealing and compression.
• Deadbolts: Deliver robust vertical or horizontal locking.
• Pins or Wedges: Additional features for advanced security.

The more locking points a multipoint lock has, the tougher it is to force the door open.

At the heart of every multipoint lock is the centre gearbox. It typically contains:

• A Latch: Retracts when the handle is pressed.
• A Deadbolt or Hook: Extends to lock the door when lifted-lever or key-wind operations are performed.

Some gearboxes include more than one deadbolt or incorporate hooks instead of a traditional deadbolt. If the gearbox fails, you can often replace it independently - refer to our dedicated Multipoint Lock Gearboxes page.

A key measurement to identify in the gearbox is the backset. This is the measurement from the front of the faceplate to the centre of the euro keyway cut out.

Another key measurement to identify in the gearbox is the Centres measurement often referred to as the PZ. This is the measurement from the centre of the euro cut out to the centre of the spindle hole.

• UPVC Multi-point Locks: Common in modern residences, often requiring roller or hook mechanisms for proper security and sealing.
• Composite Door Multi-point Locks: Similar design to UPVC but may require a different faceplate width or shape.
• Timber Multi-point Locks: Used on wooden doors and typically have a wider or adjusted faceplate to suit the thicker material.

When selecting a replacement multipoint lock it is fundamental that you select an option with the correct manufacturer, backset, centres, gearbox height, operation, faceplate width, locking points, and distance between locking points.

We offer multipoint locks from leading names, each with unique configurations:

• Avocet
• ERA
• GU
• Lockmaster
• Maco
• Millenco
• Winkhaus
• Yale
• Fuhr
• Fullex
• KFV
• Mila
• Sobinco
• Kenrick

...and many more.

Each brand supports multiple locking configurations (hooks, deadbolts, rollers etc), handle operations (lift-lever, key-wind, auto-locking, etc), and faceplate sizes. Checking the existing lock’s brand or faceplate markings ensures a smooth swap. If a specific brand or model is discontinued, we often stock a compatible replacement lock or a matching gearbox.

Several locking operations provide different levels of security and convenience:

• Lift Lever: Raise the handle to engage all locking points, then turn the key to deadlock.
• Nightlatch Locking: The latch automatically locks when the door is closed; handle-lifting secures extra locking points.
• Key Wind: Turning the key actuates the locking points, often requiring two full rotations.
• Fast Locking: Locks engage simply by lifting the handle - no key turn is required to secure it.
• Automatic Locking: Closing the door triggers auto-engagement of all locking points, with a key needed to fully deadlock.

We understand the pressures on trade professionals. Our mission is to ensure you have the right multipoint locks, cylinders, and accessories exactly when you need them.

A: Multipoint locks are door locking systems with multiple locking points (hooks, rollers, deadbolts) along a vertical faceplate. They’re common on UPVC, composite, and some timber doors, offering enhanced security over single-point mortice or nightlatch locks.

A: Yes. They distribute locking force across the door, making it harder for intruders to force entry. Additionally, advanced hooking mechanisms and improved compression benefit both security and insulation.

A: Signs include a drooping handle, difficulty lifting the handle or turning the key, partial engagement of hooks, or grinding sounds. If the door remains misaligned even after adjustments, the internal components may be worn.

A: It depends on the user’s preference and security requirements. Lift lever is the standard approach. Nightlatch offers auto-latching convenience. Key wind suits those who want tighter control, and fast locking or automatic locking systems provide quick, user-friendly closure.

A: Often, yes. If the faceplate and rods remain undamaged, changing only the Multipoint Lock Gearbox can fix many operational issues. Duffells also offer Multipoint Refurb kits for when locking points also need replacing. However, if the strip or hooks are severely worn, a full lock replacement might be more reliable.

A: Most multipoint locks accept standard Euro cylinders. Upgrading to a TS007 Rated or anti-snap cylinder maximises security. Always ensure the cylinder length matches the door thickness and handle projection.

A: A passive lock is fitted to the secondary leaf of a French door set. It typically lacks external key access, relying on shootbolts or internal handles. The “master” leaf often has the standard multipoint lock with external handle/key access.

A: Absolutely. Certain multipoint locks are engineered specifically for thicker timber or composite doors. Check the faceplate width, backset, and hooking arrangement to ensure a proper fit.

A: Measure from the faceplate edge to the centre of the spindle or keyhole. Common sizes are 35mm, 45mm, and 55mm. Accurate measurement prevents misalignment with handles.

A: Yes. If you place an order before our specified cut-off, we can often despatch for next-day delivery. We also provide LOCKer Collection points and trade counter pickups for greater flexibility.

A: Multipoint locks secure a door at multiple points along the edge, distributing force and improving weather seal - ideal for UPVC, composite, and even timber doors. A mortice lock only locks at a single central point, typically in a solid timber door. For maximum security and alignment, and a tighter seal on flexible door materials, multipoint systems often outperform mortice locks.

A: Some do. Nightlatch locking allows the door to remain latched on closure, preventing outside entry without a key. The handle inside can often override the latch for simple egress, but the exact functionality depends on the lock’s design (e.g., nightlatch vs. lift-lever).

A: Generally, they require minimal maintenance beyond occasional lubrication with a suitable non-oil-based product. Proper door alignment and hinge adjustments help maintain a lasting performance and prolong the lock’s lifespan.

A: Retrofitting is possible on certain doors, but it may require routing a channel for the faceplate and adjusting keeps. Confirm the door’s thickness, material, and hinge load capacity first.

A: Yes. We can supply Euro cylinders that are keyed alike or master keyed, allowing multiple doors to be opened by the same key if desired. Contact us for further details.
