Keep intruders out with the attractive and inexpensive Kitemarked High Security Euro Cylinder Lock from MAX6MUM SECURITY!

Does your current cylinder protrude from the outside door handle?


If so it is too big for your door and is vulnerable to lock snapping!

How to Measure the Correct Size Cylinder


We would recommend using the MAX6MUM SECURITY cylinder gauge to measure the correct size cylinder in your door, however you can also use a ruler if you choose:

1. Place the central point of the Gauge into the door’s screw fixing hole which is underneath the latch and directly in line with the cylinder – ‘C’

2. Slide the arms on either side of the Gauge to the ends of the door handle and read the measurements off the ruler strip for ‘A’ and ‘B’


This will give you 2 measurements for ‘A’ and ‘B’. As all MAX6MUM SECURITY cylinders are reversible, it does not matter whether ‘A’ or ‘B’ is to the outside of the door or not.

For the measurements, round up to the nearest 5mm, i.e. if measure meant ‘A’ is 34mm, round it up to 35mm. Put measurements ‘A’ and ‘B’ together, and this is the size cylinder you will need.


Measurement ‘A’ = 35cm
Measurement ‘B’ = 50cm
Cylinder Size Needed = 35/50 (85mm)

The MAX6 high security euro cylinder is the best choice for inexpensive home security installation. Created in accordance with the British Standards KM561977, and also awarded the “Secured by Design” approval – the police preferred specification, the 6 pin Kitemarked high security euro cylinder can be fitted to any external door in order to ward off criminals that attempt to use the most popular break-in methods.

The cylinders have been tested to EN1303:2005, and is also 1 hour fire resistant! Each cylinder is packed full of security features, and is part of MAX6’s super smooth cylinders using the Chris Belcher designed anti-bump timing pin system. This very clever system uses nickel plated hardened steel key pins and driver pins, which gives the anti-drill feature we wanted to incorporate. The Patented timing pins are designed to interrupt the timing of the pins when bumped, and it is highly effective. And because we use special pins rather than trap pins, we do not have a high expense to get this anti-bump feature! The timing pins also have inbuilt anti-picks, and mushroom driver pins, which makes them highly effective against picking.

The cylinders also have a sacrificial cut line on them. If force is applied to the end of the cylinder in an attempt to break the cylinder to gain access, on standard cylinders, the weakest part of the cylinder is the screw hole which is in the centre of the cylinder (as there is less metal here). When force is applied, the cylinder will break away at this screw hole, making it very easy to manipulate the cylinder into opening. On the MAX6 high security euro cylinder, the cylinder will break away to the sacrificial cut line only, leaving the locking mechanism intact. If the cylinder is broken at this sacrificial cut line, the last 2 pins in the chamber remain in the cylinder, meaning that the cylinder can still be locks and unlocked with the key. The sacrificial cut lines are also on both sides of the cylinder, meaning that the cylinders are reversible and can be fitted any way around.

The cylinders are ideal to be combined with the MAX6 2* Kitemarked high security door handles. We have also developed a specially sized 30/35 (65mm) cylinder which is the perfect size cylinder to use on 44mm composite doors with the MAX6 high security door handles!
