A Slide Bolt Lock, a flattened variation of the ‘Barrel Bolt Lock’, is a type of door lock that consists of a metal bolt that slides into a receptacle, or "strike plate," on the door frame to secure the door in a closed position. The lock mechanism is typically a simple design, which consists of a flat metal bolt that is housed within a metal sleeve. The barrel is attached to the door and the bolt is extended or retracted by turning a knob or key. The lock itself is a mechanical device and can be simple, but provides a secure locking mechanism that can be used in a variety of applications. The slide bolt lock is a cost-effective solution for securing a door, as it can be installed easily and do not require complex mechanisms.
