The Top 3 Security Cylinders used in the UK - Euro Cylinder - Rim Cylinder - Oval Cylinder. read on to know what they are and what they are used for!
LocksOnline being a premier supplier of security products on the net now for over a decade has been giving advice and help to thousands and thousand of people all the time, with this in mind it allows us great insight as to what concerns there are for our customers and sometime we need to go back to basics to help these people.
One of the things we get asked a lot is what is the difference between Security Rim, Euro and Oval Cylinders.
Rim Security Cylinders
You may recall if you read our articles on a regular basis that any thing with Rim in the name denotes that the lock sits on the door. But as crazy as it may sound a rim cylinder sits in the door to work a rim lock that sits on the backside of the door.
Used extensively from around the 70s onwards as the principle locking solution on a domestic house front door. If you have a wooden door and you can slam it behind you when you leave it is locked. The chances are you have a rim lock that will also have a rim cylinder. Please see the images below that denotes exactly what a rim cylinder is. The bar on the back allows you to cut it depending on the size of the door that the lock is being fitted to.
Euro Security Cylinders
The revolution of the euro cylinder back in the eighties coming from Europe to the UK has grown over the years to be probably the most familiar and most used cylinder now in the locking industry. This cylinder you will find in all walks of life, probably every UPVC door will have a euro cylinder fitted as a matter of the norm. I am not aware why it was called euro cylinder or why it is shaped like a key hole, perhaps one of our learnd Master Locksmiths in the UK may like to reply as to why this is the case.
Euro Cylinders are available in different sizes and can have a turn (Thumb Turn) on the inside. These cylinders are normally measured from the centre fixing hole, to either end. most UPVC door locks may sit off centre to the centre of the door and therefore, it is critical to get the correct measurement by measuring this off set. In recent years these cylinders have become victim to being snapped with relative ease. the biggest problem with this is poor fitting, using the wrong size cylinder etc. responsible manufactures, have tried hard to keep their cylinders up to a proper grade and a BS EN 1303 cylinder is really now the benchmark that you need to consider if you are wanting to change your cylinders.
Oval Security Cylinders
Brought out by Union back in the 70s perhaps to compete with the Euro European Cylinder or perhaps to increase the master key permutations of the old 3 and 4 lever master keyed sash locks from that era. I am not sure as to the exact reason but the system was taken over by Everest Doors in the 80s and used on commercial projects and the old PSA on government buildings, schools, hospitable etc.
Not very much seen in domestic properties as principle locking solutions and to be honest this system seems to be loosing ground in the UK as a viable locking solution especially with so much imported locks coming in set up for Euro Cylinders.
Oval Cylinders normally came in three sizes, again measured from the centre to either end, 30x30 35x35 and 40x40 also they come with a thumb turn option.
I hope you have found this article informative and like I mentioned if any of my fellow locksmiths out there may be able to add comment as mentioned above, please come and make your views below.
