Four Kinds of Locks



These are often located on the exterior portion of the door, while the interior side features a lever or traditional knob with either a thumb turn, deadbolt or even a keyless entry system. Handle grips with locks are another option for exterior door hardware. These are available separately or as part of a lockset.


Door knobs are made of many materials, including wood, ceramic, glass, plastic and different types of metal. Brass is one of the most popular materials because of its excellent resistance to rust. Doorknobs have been used around the world for centuries and were first generated in the United States in the mid 19th century. Round or ball-shaped door knobs is still commonly used even though it’s considered as the hardest to turn. Egg-shaped door knobs are the easiest.


There are different kinds of hinges, from ones that will make it easy to remove your door from its jamb to options that can handle the extra weight. Hinges attach to the sides of the doors to secure your door to the jamb and allow it to open easily. While you may not see these at first glance, they are an important functioning part of your door’s hardware, and they can be seen when the door is open, which means you’ll most likely want to match their finish to that of the other hardware you use on your door.

Deadbolt Locks

This offers more security options against the burglar who relies on gaining access to homes by breaking through the door glass and turning the thumb turn to open the door. Single cylinder deadbolts are operated with a key from the outside and a thumb turn from the inside. A double cylinder deadbolt is operated with a key from both outside and inside the door. Both types of deadbolts are available separately or as part of a lockset and are relatively inexpensive, depending on the model you choose.
