دانلود کتاب Drilling Open & Bypassing Locks: (Why Every Building Needs High Security Products & Alarms)

Given enough time, anybody can drill open or bypass just about any kind of lock. Whether those locks are residential grade locks, business locks, padlocks, vending machine locks, or high-security locks, they can all be compromised. Every home and business must consider additional layers of security if they are going to protect their property. Such additional layers can be things such as high-security locks, drill resistant locks, free-spinning lock collars, alarms, video surveillance, panic bars, and the Exit Security Inc. "Ring Bolt". There are also times when locksmiths need to drill lock cylinders in order to get doors opened and re-keyed. This book will discuss how these methods are used. This information is already in circulation throughout the world and is available to anybody and everybody. However, David offers solutions to the problems of lock bypass methods. Included in this book is David's exclusive and original technique for making the Exit Security Inc bar more secure than the inventors ever intended for it to be. This is a short and "to-the-point" book on this subject and lays out the principles you as a locksmith need to know in order to better protect your customers. This is one of many books on lock work that David has made available.
