3-Star Kitemark Logo = Anti-Snap lock protection

The Kitemark logo can be found anywhere on the lock; it is usually found on either, the front or side of the euro cylinder.

 

6. What Standard Euro Cylinder Lock Should I Fit?

To protect your door locks from lock snapping there are three ways to go.

OPTION 1 – Sold Secure 312 Diamond Approved Cylinder

Fitting a Sold Secure Diamond approved cylinder ( SS312 ) will help prevent being burgled as this standard of euro cylinder is tested against lock snapping methods used by criminals.

 

>> West Yorkshire Police recommend using an SS312 Diamond Cylinder 

OPTION 2 – TS007 3 Star Kitemark

If an SS312 Diamond cylinder is not used, your euro cylinder lock should at least reach the TS007 3 star Kitemark standard to provide true resistance to snapping.

If it’s not Sold Secure diamond make sure a cylinder at least has a 3-star kitemark

IMPORTANT: Don’t rely on the manufacturer stating its snap resistance; you should always look for 3rd Party approval to confirm a product’s performance.

>> TS007 3-Star is recommended by West Yorkshire Police 

OPTION 3 – 1 Star Kitemark Cylinder with 2 Star Door Furniture

7. How should a Euro Cylinder Lock be fitted?

It is vital the euro cylinder lock on your door is fitted correctly, as lock cylinders vary depending on the door and handle thickness.

Incorrectly Fitting Euro Cylinder Locks – can lead to Lock Snapping.

If the cylinder is sticking out by a large amount ie more than 2mm then its not fitted right.

The more of the cylinder that is accessible, the more prone it is to snap

Again if the cylinder is overhanging by a large distance ie more than 2mm then its fitted wrong, the cylinder should be fitted flush to the handles.

 

How to fit a Euro Cylinder Lock correctly:

The cylinder should not protrude more than 2mm from the handle

Ideally should be completely flush with no external overhang.

The correct size of the cylinder it vital.
