Locking system DU with 3D key sectionsContract business
“DU” means “Double Undercut”, which directly points to the most important feature against unauthorised copying of keys: the double undercut on the lateral key sections. The resulting three-dimensional groove cannot be copied by conventional copying devices which exclusively copy in two dimensions.
This locking system, which is patent-protected until 2031, can be adapted individually and gradually to the most varying requirements. Depending on its features, it even complies with the most stringent requirements in accordance with DIN 18252, DIN EN 1303 and the VdS guidelines.
Especially designed for upscale industrial buildings, this system satisfies the complex requirements of a building on organisation, convenience, economic efficiency and of course security.
Two optional swivelling levers arranged on one side and acting on a locking bar serve as a highly-effective locking element which performs a double security scan over the length of the key section.
