Again, not a particularly exciting topic, however very important. The deadbolts are a primary form of household safety and security. Here’s a technical tidbit: The deadbolt lock works by effectively bolting the door into its frame. The bolt is “dead” in that it has to be manually moved in and out of place by means of a key or knob. There are three basic parts of deadbolt lock: a key-accessible outside cylinder, the “throw” (or bolt) which slides in and out of the door jamb, and the thumb-turn, which allows for manual control of the bolt from the inside of the home. A standard horizontal throw extends one inch beyond the edge of the door and into the jamb. All deadbolt locks should be made of solid steel, bronze, or brass; die-cast materials are not fashioned for great impact and could break apart. Now you know.
