The unique, patented construction of the Abloy Protec rotating disc cylinder makes it virtually pickproof. Keys and discs use a new principle where cuts are made on two different radii.
The keys in this system can not be duplicated. With 1.97 billion different combinations per keyway, the unique ABLOY® PROTEC rotating disc cylinder offers extensive master-keying possibilities and enables locking systems to include thousands of doors and employees. This is the highest security level of the Abloy® line and is ideally suited for all commercial, residential and institutional applications.
