Do you have children or are you in an environment where there are children? If yes, then you can certainly understand that children are generally very excited. Of course, when kids are running around your house, there's a chance they could get hurt, and that's exactly what happens when they're caught by an unexpectedly opened door.
While it's not possible to completely stop children from running around your home, there are steps you can take to ensure their safety. This anti-collision doorknob cover is an excellent example of these safety measures. Installing these doorknob covers on your home's doorknobs will help improve safety by ensuring your children don't get hurt even if they run into a doorknob.
