What to look for when buying deadbolt locks

  • No matter what type of deadbolt locks you buy, there are certain important points to be kept in mind while purchasing a deadbolt lock. It is recommended to go for a deadbolt lock that has been rated grade 1 as it has been tested with at least 250,000 open/close cycles and has a bolt that is inserted at least 1 inch into the door frame. Also, a grade 1 deadbolt lock can withstand a minimum of 10 hammer blows before giving way. Always avoid cheap locks with no ANSI ratings.
  • Avoid purchasing a double cylinder lock. In an emergency using a double cylinder lock may land you in a difficulty while escaping from your house.
  • Underwriters Laboratory is another very well-known and respected organization that tests various types of products and develops standards for them. In order for a deadbolt lock to meet UL 437 standards, the lock must be able to resist various types of attacks, such as: drilling, picking, prying and hammer attacks. So, always look for the underwriter’s UL 437 rating on any deadbolt lock you purchase.
  • Whenever purchasing a deadbolt lock never purchase a lock which havescrews less than 3inches in length. Longer screws that are used to attach the strike plate of the lock will allow you to insert the screws not only into the doorjamb, but into the door frame as well. The door frame is significantly stronger than the doorjamb and will further increase resistance and door strength should someone try to push through the door.
