A lockset is a complete assembly that includes a lock and its associated hardware, designed to secure a door. It typically consists of a doorknob or lever, a locking mechanism, and a strike plate that is mounted on the door frame. Locksets come in various styles and finishes, allowing them to match different door designs and home aesthetics. Locksets can be categorized into different types, such as deadbolts, knob locks, and lever locks. Each type offers varying levels of security and ease of use. When choosing a lockset, factors like durability, security rating, and compatibility with the door are important to consider.
