Anti-snap locks Rotherham

Lock snapping is on the increase! The lock on a upvc door is called a euro cylinder. This is made of mainly brass. This helps with lifespan of the cylinder in that it is virtually maintenance free. The problem with brass is that it a soft metal. The euro cylinder is held in by a “retaining” screw. At this point the cylinder has a “weak” area, which if enough force is applied in a specific way, allows the cylinder to snap in half!
