Quick answers and guides to the most common everyday questions from window and door manufacturers and fitters.
A Eurogroove is an industry standard feature on most PVCu, aluminium and timber door and window profiles, where the locking devices are fitted.
A Eurogroove is the groove in the profile in which multipoint locks and espagnolettes are fitted. This is always 16mm for PVC, but can be 20mm in Timber.
Tools required:
View the video for full details on fitting.
Lateral and height adjustment:
The lateral alignment of the Patriot Plus Hinge can be adjusted by +/-6mm
The height can be adjusted by +8mm

The compression of the Patriot Plus Hinge can be adjusted by +/- 1.5mm
PAS 24 is an enhanced security performance test for door assembly requirements, every component used within the door set tested must comply to the relevant British Standard for that component.
PAS 24 includes several security tests, such as:
An example of the intensity of the testing, the mechanical loading tests subjects the door set to 4.5Kn of pressure, the equivalent of approximately 45 times the pressure used to tighten a car wheel nut.
TS 007 is a security standard relating to the door handle and cylinder combination used on a door. To achieve TS 007 status, the combination used must total 3 stars.
A cylinder can achieve either 1 or 3 star classification, where as a door handle can only ever achieve 2 stars.
Therefore, it is possible to achieve 3 star accreditation by combining a 1 star cylinder with a 2 star door handle. Or, just using a 3 star cylinder alongside an unaccredited door handle. See our simple diagram below.
Achieving TS007 is vital in order to pass any door to PAS 24 or achieve Secured by Design.
Anti-Snap – the cylinder has a section or sections, often called a sacrificial cut, either side of the central lock mechanism that will come away if the cylinder was to be attacked from the outside, however leaving the remainder of the cylinder mechanism intact and locked.
Anti-Pick – the top half of the pin stack inside the cylinder are designed to include a mushroom shape or indent. Therefore, if something was used to pick the cylinder it would catch on the pins and prevent the cylinder from unlocking.
Anti-Bump – cylinders are designed to have more pins (generally 6) and a shallow pin stack. By doing this it means that if a bump key was knocked into the cylinder, the pins would not jump up meaning the cylinder could not be bumped.
Anti-Plug/Core Extraction – the cylinder has strengthened steel circlips that hold the cylinder in place so the core cannot be extracted from the cylinder.
Anti-Drill – the cylinder has plates and pins built in and this prevents the cylinder core being turned if the pin stack was attacked by a drill. It is designed to break the drill bit and protect the integrity of the cylinder to prevent entry.
Restricted profile cylinders / key systems are non-duplicable, meaning it’s impossible to purchase blank keys in the market and create fraudulent keys. These cylinders provide a higher level of security.
On the other hand, open profile cylinders mean that any key cutter on the market can make replacement cuts and the cylinders can then be mastered from this. This can sometimes be a homeowner’s preference as it is easier to get additional keys cut.
BS EN 1303 is a British Standard relating to cylinders. It is broken down into 8 digits and ensures that the cylinders are tested to the highest standard. The 8 digits are; Category of Use, Durability, Test Door Mass, Fire Resistance, Safety, Corrosion and Temperature Resistance, Key Related Security and Attack Resistance.
Cylinders are graded based on this criteria.
Step 1: Open the door and loosen the door handle fixing screws slightly, or remove them and the handles completely
Step 2: Unscrew and remove the cylinder fixing screw
Step 3: Put the key in the cylinder and slightly turn it until the cam tongue is aligned, once this is aligned you can pull the cylinder out, (generally the key will point to around 5 to or 5 past on a clock face)
Step 4: Replace with the new cylinder and then repeat the process in reverse order
A free movement cylinder allows a key to operate the cylinder even when there is already a key inserted in the other end. These cylinders are for use on emergency exit door lock kits such as the FUHR 870 and 871. This function ensures that when the panic bar or panic lever is pushed the cam will rotate freely and allow use at any time.
This type of cylinder is also recommended for use with the FUHR 881 Electromechanical Door Lock.
There are three popular types of door handle. Refer to our website or catalogue for the full range of brands, designs and colour options.

Lever/Moving Pad
Lever/Fixed Pad
Yes, this system is called keyed alike. It is where one key can open a group of keyed alike cylinders, so for example someone’s front door key could also unlock their patio doors and back door. All of the euro profile cylinders supplied by Carl F Groupco have the option to be supplied in this way.
You can also opt for a master key system, this is useful for buildings where different types of access are required, usually in hotels or where building management is required. This usually isn't recommended for standard domestic properties.
Step 1: Measure the overall length from the bottom part of the cylinder
Step 2: Measure from the centre screw hole to each end, these two measurements combined should be equal to the overall length
OR
Step 1: Measure from the centre screw hole on the door lock to the face end of the cylinder on each side, these two measurements will be equal to the overall length
Backset
The backset is the dimension from the front of the faceplate to the centre of the handle spindle or cylinder hole.
The most popular backset sizes are 25mm, 30mm, 35mm and 45mm.
The backset dimension is the distance between A and B on the diagram.
PZ Centre
The "PZ" or "Centre" is the distance between the centre of the handle spindle and the centre of the round section of the cylinder.
The PZ Centre dimension is the dimension between C and D on the diagram.
Multipoint locks can have one or two spindle holes (also known as followers) these type of locks will have two measurements, the most popular being 62mm / 92mm.
Most modern locks with one spindle are 92mm centre, however some older locks may be 70mm or 72mm.
On most FUHR locks, to change the handing you remove the small grub screw on the side of the lock case adjacent to the latch plate with a 2mm allen key.
Remove the latch and turn in it 180º vertically, place it back into the opening and secure the grub screw back in place.
The FUHR 871 and FUHR 881 door locks are supplied handed, this cannot be changed, so please ensure you order the correct handing for the application.
Step 1 Unscrew and remove the 3 screws as shown in the video
Step 2 Remove the lockcase
Step 3 Clip the replacement lockcase in place
Step 4 Replace the 3 screws
Hook and Keep alignment:
The hook and keep should be aligned using the guideline on the hook plate. Ensure the hook engages correctly avoiding friction on which can result in damage to the hook, there should be a 2mm gap between the line on the hook plate and the flat of the hook as shown in the diagram.
Latch and hook adjustment:
Take care not to over adjust the hook keep as this can damage the keep - do not rotate through 360º. A screwdriver and a 4mm allen key will be required when adjusting these plates.
Roller and mushroom adjustment:
Adjust eccentric compression of roller and mushroom keeps to ensure the optimum compression for the door. Adjust the compression using a 4mm allen key.

Why are there new Part F regulations?
The Future Homes Standard 2021
What products can I use to comply?
As windows now make homes more airtight, additional ventilation is required to circulate air in living spaces. Options include mechanical ventilation, extractor fans and trickle vents.
Trickle vents are by far the cheapest and most practical solution to achieve the regulations for both new build and replacement markets.
What are the new regulations?
for dwellings regarding ventilation....
New build and extensions:
Replacement Market:
New reporting, compliance and certification required by installers from June 2022.
Always refer to the government regulations, download the full document here: https://www.gov.uk/government/publications/ventilation-approved-document-f
On closing the door, the latch depresses.
A magnet which is built into the keep/striker engages the latch.
The latch throws 20mm into the keep/striker and deadbolts.
The latch remains secure and locked until the the door is unlocked.
Step 1 Remove the magnet from the frame
Step 2 Close the door until the tappets on the hinge side touch the contact plate (don't fully close the door)
Step 3 Place the magnet against the small circule within the magnet part of the door lock
Step 4 If the hook locking points extend, then the lock is working correctly.
