To keep your home safe, be sure you have proper window locks and window latches for your windows. Window locks are an important part of securing windows in your home. Without them, anyone can open your windows from the outside. While locks are not the only security measure you should take, they are essentially the first line of defense toward an intruder. Many burglars will try to enter a home through an unlocked window, so installing proper window locks can help to deter them from doing so. In addition, a window hasp can also help to prevent accidents and injuries caused by windows opening unexpectedly.
