What parts does Door hardware include?

Door hardware includes knobs or handles and all latching and locking mechanisms. This is technically called a lock set whether or not the hardware contains a lock. Different lock-sets are designed for different applications. Once you have determined the decision on the type of lock set required for your application, you can focus on the style and finish of the hardware. Keep in mind that no matter which type you choose, a quality lock set is usually worth the extra cost and will perform better and last longer than inexpensive hardware.

This passage is going to talk about the followings of door hardware applications:

1) Door Knob Types

2) Door handle connection

3) Latching and locking mechanisms

1) Door Knob Types

While you may want a door handle to be round or square, it may not be a knob at all. It can be a lever handle or a knob kit, which is a combination of a thumb latch and a handle used on exterior entry doors. A lever handle is easier to grip than a door handle and is an approved operating device that meets ADA (Americans with Disabilities Act) or accessibility or barrier-free design requirements.

Door handles are not permitted for this purpose because they require a firm grip or pinch on the knob and a twist of the wrist to operate. Although ADA compliance is required in commercial buildings (not in your home), lever handles can make doors easier to use for everyone.

2) Door handle connection

 

It is also worth noting that the door handle is attached to the lock spindle differently. On older door hardware, the door handle is secured with an exposed set screw that secures the knob to the square threaded spindle. When turned, the spindle rotates and operates the latching mechanism. The downside to this type of fastening (besides the unsightly set screw) is that door handles often become loose and can end up spinning in your hand.

The current popular method of attaching door handles to spindles does not use screws at all, but instead uses a hidden device called a brake. This type of "screwless" door handle can be easily removed with a small flathead screwdriver.

   

3) latching and locking mechanisms

 

Different form door knobs or handles, the door latching is a simple closing device commonly used on internal doors where no lock is needed. The simple door latching is available in a staggering variety of different sizes, shapes, and quality levels. 

As a small detail in the project is often overlooked, we suggest that you should take a certain degree of consideration into type of door latch, because it is the project that has the largest single impact on the operation of the new door handle.

Security door locks are very important when guaranteeing safety in different places. These systems are not only useful in homes, but are also essential for the functioning of different types of occasions, such as schools, offices, shopping malls, etc.  

Depending on the occasion where they will be used, different types of locks will be required. In the other articles on our website, we tell you about the different types in existence and how to choose the most suitable.
