This book is again a must have for any safe technician doing high security safe openings. I have never gotten a call for a high security safe opening that I did not go to this book first to see what I might encounter. This book will tell you the door thickness to the lock, door thickness to bolt center, type of combination lock and mounting, if glass is present, relocker information, handle rotation, and a recommended opening technique.
Includes safes by the following: Bernardini, Bischoff, Chatwood-Milner, Chubb, Fichet-Bauche, ISM, Kaso, Lord, Original, SLS. Over 225 pages of complete openings. Each safe described with many photos. Contains many FULL PAGE photos. Very detailed opening procedures.
