Throw
Definition and meaning of Throw in real estate.
A throw is the distance that a deadbolt latch extends from the edge of the door into the strike plate on the door frame when the lock is fully engaged.
In more detail
The length of the throw is a critical factor in home security, as a longer extension makes the door more resistant to forced entry. Most residential deadbolts feature a throw length of either one-half inch or one full inch. A lock with a one-inch throw is generally recommended for exterior doors because it penetrates deeper into the door frame structure. Properly aligning the deadbolt with the strike plate ensures the throw can extend fully and lock securely.

Frequently asked questions
Why is a longer throw more secure?
A longer throw embeds the bolt deeper into the wooden or metal door frame, making it much harder for an intruder to pry the door open.
What happens if a deadbolt throw does not extend fully?
If the bolt cannot extend to its full length, the internal locking mechanism may not engage, leaving the lock vulnerable to bypass.
