Understanding How Door & Door Knobs Work: 6 Useful Tips for DIY Projects


Door knobs are one of those house components we use every day but don’t really think about. We just expect them to work without giving them much thought. But if you’re embarking on a DIY project, it’s essential to understand how they work so you can install them correctly.

This article will give you six tips for understanding door knobs and getting the most out of your DIY projects.

1. Know Your Door Knob Types

Different types of door knobs can be very helpful to know when undertaking DIY projects around the house. Not only will different door knob types offer different visual aesthetics, but they can also be more or less functional for different purposes. Here is a quick guide to some of the different types of door knobs available on the market:

  • Dummy Door Knobs: Dummy door knobs are purely aesthetic and do not function. They are often used on double doors where one door is inactive.
  • Knobset Door Knobs: Knobset door knobs have a round knob that turns to open the door. They are most commonly used on interior doors.
  • Lever Handle Door Knobs: Lever handle door knobs are operated by pushing down on a lever rather than turning a knob. They are most commonly used on exterior doors.
  • Deadbolt Door Knobs: Deadbolt door knobs have a bolt that must be turned to open the door. They are often used on entry doors for added security.

Now that you know some of the different door knob types available, you can make a more informed decision about which type is right for your needs. Different door knobs can offer different levels of security, privacy, and aesthetics, so choosing the right one for your home is vital.

2. Understand the Parts of a Door Knob

Door knobs come in many different shapes and sizes, but they all serve the same purpose: to open and close a door. But have you ever stopped to think about how a door knob works? Or what the different parts of a door knob are called?

If you’re planning on undertaking any DIY projects that involve door knobs, it’s helpful to understand the parts of a doorknob and how they work. This will help you avoid potential problems and ensure that your project is a success.

The central part of a door knob is the round, cylindrical portion that you grip to turn the knob. This is known as the “knob rose”. Attached to the back of the knob rose is a rod or spindle, which is what turns the latch or bolt that opens the door.

The knob rose is usually attached to the door with two screws, which go through holes in the door and screw into threaded sockets in the back of the knob rose. Sometimes, there may only be one screw, or the screws may be hidden from view.

The part of the door knob you see on the other side of the door is known as the “plate”. The plate is usually screwed or bolted to the door. It has a hole in it for the spindle to pass through, and sometimes it has a key slot.

On the inside of the door, there is a mechanism known as the “latch” or “bolt”. This is when the spindle from the door knob turns to open or close the door. The latch is usually mounted on a plate that is screwed or bolted to the door frame.

If you’re planning on replacing an existing door knob, you must make sure that the new one you choose is compatible with the existing latch or bolt. Otherwise, you may not be able to open or close the door!

3. Consider Your Installation Options

There are two ways to install a door knob: a screws-through-the-door method or a concealed installation method. The screws-through-the-door method is simpler and easier to do yourself, but it isn’t as aesthetically pleasing. The concealed installation method is more difficult and requires special hardware, but it gives the door a cleaner look.

4. Choose the Right Door Knob for Your Project

Door knobs are not only functional but also add a decorative touch to your doors. Various types and styles of door knobs are available, so it is important to choose the right one for your project. Here are some things to remember when selecting a door knob:

  • Functionality: Door knobs come in various functions, such as privacy, passage, and dummy. Make sure to choose the correct function for your needs.
  • Style: Door knobs come in many styles, from traditional to contemporary. Select a style that compliments the overall look of your home.
  • Finish: Door knobs are available in various finishes, from brass to bronze. Choose a finish that compliments the other hardware in your home.
  • Installation: Some door knobs are easy to install, while others require special tools or instructions. Make sure you know what is required before you purchase a door knob.

By keeping these things in mind, you can be sure to choose the right door knob for your project. Door knobs are an important part of any home, so select the perfect one for your needs!

5. Install the Door Knob

Once you’ve chosen the right door knob for your project, it’s time to install it. If you’re using the screws-through-the-door method, start by drilling pilot holes through the door. Then, insert the screws and tighten them until the door knob is secure. If you’re using the concealed installation method, start by attaching the mounting plate to the door with screws. Then, insert the shank of the door knob into the mounting plate and secure it with a set screw.

6. Test Your Door Knob

Once you’ve installed your door knob, it’s important to test it to ensure it works properly. Open and close the door a few times to make sure the knob turns smoothly. Then, try locking and unlocking the door (if it’s an exterior door) to make sure the mechanism works properly. If everything seems to be working fine, your door knob is ready to use!

These are just a few tips for understanding door knobs and getting the most out of your DIY projects. With these tips in mind, you can be confident that your door knobs will work correctly and add a touch of style to your home.
