Sterling has expanded its popular Euro profile cylinder category with the launch of two new British Standard Kitemarked cylinder ranges. Building on the success of Sterling H-Series Snap Safe six pin cylinders, the new DoorMinder 3 and 1 Euro cylinders have been indepently tested to and passed the latest TS007:2014 standard. Sterling’s 3 and 1 Kitemarked DoorMinder ranges feature anti-drill, anti-pick and anti-bump protection and are Snap Safe. The 3 Kitemarked DoorMinder cylinders offer further enhanced security by incorporating an innovative locking cam mechanism, which is automatically engaged when the key is removed.
