Many people use a door chain to add extra security to their home entryways. These security devises allow you to open a door only slightly so you can see who is on the other side before letting them in.
These chains are easy to install; simply attach one side to the door and the other to the wall. When choosing a door chain, be sure to look for one made of a strong metal, like stainless steel. The thick links and secure bolts will give you true peace of mind for your home.
