Sterling has expanded its popular Euro profile cylinder category with the launch of two new British Standard Kitemarked cylinder ranges. Sterling’s 3* and 1* Kitemarked DoorMinder ranges feature anti-drill, anti-pick and anti-bump protection and are Snap Safe. 3* Kitemarked DoorMinder cylinders offer further enhanced security by incorporating an innovative locking cam mechanism, which is automatically engaged when the key is removed. DoorMinder ranges cover all sizes from 70mm to 100mm and are available in double cylinder and thumbturn variants. The Kitemarked cylinders come in a satin nickel finish, feature a standard section keyway and are available with either keyed-alike or master key options.
