Anti Snap Locks - Euro Cylinder

Anti Snap Locks - Euro Cylinder

Our Anti Snap Euro Cylinders for uPVC and Composite doors offer extra security from a lock snapping attack, with sacrificial brake off points on both ends. This function would prevent a potential attacker from gaining access to the cam that locks and unlocks the mechanism. When the incorrect size euro cylinder is installed, it can protrude from the handle and be grabbed hold of with various tools. Even if the lock is the correct size, the handle could potentially be removed and the cylinder would be exposed. With our new Vital Anti Snap Euro Cylinders, this vulnerability is eradicated. Now available in a dual finish with a nickel body and a brass plug. This attractive design is suitable for both silver and brass handles. 

How to Measure a Euro Cylinder Door Lock?

In order to make sure you get the correct size and type of euro cylinder lock you require, you firstly need to identify if you have a double (takes a key at both ends), a thumb turn (has a knob on the inside and most commonly seen on flats and apartments to meet fire regulations), or a half euro cylinder (mostly seen on more modern up and over garage doors, and housed in electric shutter control boxes). Half euro cylinders have an adjustable cam so it can be adjusted to the angle required within the lock housing, as these differ on garage doors and shutter control boxes from a conventional uPVC locking mechanism.


In millimetres, please measure from the central fixing hole to the edge and then repeat on the other side. Please note that this may give measurement of equal or different amounts on each side.
