Why you need Ultion high-security door locks

Choosing high-security locks is an effective means of keeping thieves at bay – and Ultion can help you do just that. This particular type of lock has been approved by the police, as well as having being put through rigorous tests by British Standards and the Master Locksmith Association. Ultion locks have also been awarded the highest TS007 three-star standard.

Designing out crime

There are many in-built features that make Ultion locks superior to others on the market. They boast 11 security pins capable of creating 294,970 different combinations, seriously reducing the chances of thieves guessing the right one.

Ultion locks also have a strong molybdenum core that is 25% denser than iron. This protects your property from lock snapping, drilling and bumping, further improving security.

As soon as Ultion locks detect that tampering has occurred, they will enter into lockdown mode. A lock will move into the central cam, which is kept in place by a retaining pin that means it’s impossible for the lock to be damaged.

A lock suitable for any door

Another advantage of Ultion locks is they can be fitted to any door. Whether you have aluminium doors at your property, uPVC or even wood, an experienced Doncaster locksmith will be able to fit them to the required standard. The premium components used to make Ultion locks will stand the test of time and keep your property safe for years to come.

Here at S Fretwell & Sons, we offer a snap-proof lock package to help give you complete faith in your home’s security. For one low price of £210, you will get three Ultion locks – one fitted to your front door, one to the back and the final for your French or patio doors.
