Ultion TS007 3 Star Sold Secure Diamond Cylinder

The Ultion cylinder is one of the most secure on the market - so much so infact that no test has beaten it. The cylinder has passed all major British standards test for security without the need for cylinder protectors or extra secure door handles. These tests include the highest TS007 standard (3 star) and the extended Sold Secure Diamond test, which is more rigorous and designed by the Master Locksmith Association.


Ultion cylinders feature a ‘Lock Down Mode’ when it detects forced entry and activates an attack lock directly into the central cam. Even if the most determined intruder gets past Ultion’s two sacrificial sections he won’t get to the attack lock because it is protected deep inside a solid molybdenum core and secured with a dedicated retaining pin.

Even after an Ultion cylinder has thwarted an intruders attempt, the door can still operate the lock normally from inside - leaving the homeowner in complete control of their security.
