If you look at a standard door, you’ll see three major parts that while keep it secure. The first two parts are called the lockset and consist of the handle and the latch. Also, the handle is the device that you grab and turn to open the door. Importantly, the latch is the small metal bolt that you will see sticking out of the side of the door when the door is open.
The third part is the strike (known as the strike plate), which looks like a metal plate along with a hole for the latch to rest inside. in addition to this, an electric strikes replaces the fixed strike. Usually, it presents a ramped surface to the locking latch allowing the door to close and latch just like a fixed strike would.
