A latch lock is one of the most essential and widely used locking mechanisms in modern homes, offices, and commercial spaces.

Their versatility, affordability, and ease of use make them a popular choice for interior and exterior doors alike, ensuring both functionality and peace of mind.
What is a Latch Lock?
A latch lock is a type of door locking mechanism that uses a spring-loaded latch to keep the door closed. When the door is pushed shut, the latch automatically engages with the strike plate, securing the door without the need for a key. It can be opened by:
Turning a handle or knob Using a key (in some models) Pressing a lever How Does a Latch Lock Work?
The working mechanism of a latch lock is simple:
The latch bolt is angled and spring-loaded. When the door closes, the latch retracts slightly. Once aligned with the strike plate, it snaps into place. Turning the handle retracts the latch and opens the door.
This automatic locking feature makes it highly convenient for daily use.
