The intruders usually do not attempt to undertake any sophisticated methods to open your door, but we only facilitate their job having entry doors with single deadbolt very popular in Canada and USA. Our conventional entry doors are "sweet chocolate" for intruders. They just kick in and demolish flimsy door construction letting them to get inside within few seconds. Watch how easy they do that
Therefore, with respect to our personal and our family's safety, as well as of our material property, it is a good idea to invest in a good, anti-burglary door.
