What is the latch lock body? What are the functions?

  The latch lock body is very common among the entrance doors in Southeast Asia. The touch-type ball lock body can open the door by pulling or pushing it open, without a door handle. The door can be prevented from being opened by strong wind when closing the door. The handleless lock body design is very convenient in life. Due to the special opening and closing method of the lock body, the selected lock body material must be strong, durable, and not easily damaged.
