Questions & Answers

Our CFG cylinders are of high quality and reliability, they have been tested to BS EN 1303:2015 achieving Grade 6 classification. The test report is available upon request, the report confirms that the cylinder passes all relevant aspects of the test, the cylinder classification is detailed below:

  • Category of Use: 1
  • Durability: 6
  • Door Mass: 0
  • Fire Resistance: 0
  • Safety: 0
  • Corrosion & Temperature: C
  • Key Related Security: 5 (when used with cylinder protection)
  • Attack Resistance: D

CFG brass cylinders are available with polished brass or nickel plated finish. Key to differ, keyed alike, keyed alike pairs, knob operated and half cylinders are all available.

  • Key to differ: Each cylinder will be operated only by the keys cut to that particular cylinder
  • Keyed alike: each keyed alike cylinder uses the same key.
  • Keyed alike pairs: two cylinders supplied with 6 of the same keys – any one of the keys will operate both cylinders. Ideal for double doors. Each pair has a different key
  • Knob operated: key is used on the external face, on the inside, a knob is used to turn the cylinder.

All of the CFG cylinders are supplied with 1 x M5 x 40mm fixing bolt and 3 x keys. The cylinder is “open profile” allowing keys to be cut without restriction. Key blanks are available if further keys are required.

How to replace a euro cylinder?

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

How to measure for a replacement euro cylinder

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

How do I achieve TS 007 on my doors?

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.

What is anti-snap, anti-pick, anti-bump, anti-plug extraction and anti-drill?

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.

When would I need a free movement cylinder?

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.

What does a master key suite mean?

This cylinder key system is used where you need to provide different levels of access to different people within a building. For example, a system could allow for cleaning staff to be able to unlock all cylinders in an office, but only allow individuals to unlock their personal office door.

What is the difference between restricted and open profile cylinders?

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.
