Quick answer
Anti-snap euro cylinders are designed to resist lock snapping, a quick burglary method used on uPVC and composite doors. Look for TS007 3-star or SS312 Diamond marks.
What is lock snapping?
A standard euro cylinder has a weak point in the middle. Burglars can snap it there and open the lock in seconds.
How anti-snap cylinders help
They have a sacrificial section that breaks away while leaving the locking part intact, plus protection against picking, bumping and drilling.
Which marks to look for
TS007 3-star kitemark (or a 1-star cylinder with 2-star security handles), or Sold Secure SS312 Diamond. The cylinder should sit nearly flush with the handle.
