How can a Finesse door stand up to this type of attack?
The Master Locksmiths Association are very clear in how to prevent blowtorch burglary; in simple terms ‘Fit a SS312 Diamond Approved Anti-Snap cylinder to to your uPVC Door.’
Every Finesse door is fitted with a high security Ultion cylinder and is therefore impervious to this type of attack. During an attempted break in, a special double pin inside the cylinder fires in such a way that the cylinder cannot be snapped; this is true regardless of the attempted method of entry, assisted by blowtorch or not, with the same result.
We insist on using Ultion cylinders because we care about the products we design, manufacture and install in your home. Ultion is listed on the Master Locksmiths Association website as the most secure cylinder available and it has been specifically designed to combat this type of attack. Please see this video which helps to explain more about the unique design of Ultion cylinders
