A lockset is a collection of hardware components that work together to secure a door. It typically includes a lock, a handle or knob, and sometimes a latch or deadbolt. 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 knob locksets, lever handle locksets, and deadbolt locksets. Each type serves a specific purpose, with some providing higher security than others. Proper installation and maintenance of a lockset are essential for ensuring safety and functionality in residential and commercial spaces.
