Anti snap cylinders
Whilst there is a lot of scaremongering on various websites out there about anti snap cyinders and the specific types of vulnerabilities that euro cylinders (the most common form of locking device used in UPVC and composite doors) are liable to the important thing is not to panic. professionally specified and fitted cylinder will help protect you. I recommend the use of anti snap cylinders as these have been tested fully against all known MO’s for burglars. I have plenty of these on board and would be happy to assist, advise and fit as necessary.
