Dead Bolt Lock

Home security is most important these days and dead locks are pre-eminenet for security of a home or a business firm. Dead bolt locks are supposed to offer the best protection, and hence should be used on all exterior doors. You have to be sure that the locks you use have bolts that extend at least one inch into the wall, and that the locks are made of solid metal with no exposed exterior screws. Some dead bolt locks are also available with free-spinning collars which prevent intruders from removing the cylinder with a wrench or vice grips. It is called "dead" because there are no springs to operate the bolt. The lock is only operated manually with a key or a thumb turn from the inside.

Types of Dead Bolt Locks

• Single cylinder lock: Single cylinder locks operate with a key from the outside and a thumb lever on the inside.
  
  
• Double cylinder lock: Double cylinder locks use a key both inside and out. These locks offer better protection. For instance, if a burglar enters the house through a window, he cannot open the door without a key. Double cylinder locks can also pose a fire safety hazard, so you must consider your options and choose the best solution for your home.
  
  
• Vertical dead bolt: This is another lock option. These locks are used primarily to secure double doors. The vertical dead bolt lock is secured to its mating plate with pins that make it difficult to pry. Vertical dead bolts are also available in single or double cylinder models. Dead bolt locks must be locked when you leave your home. If you pull your door shut and walk away, the door is not locked.
