Barrel bolt is a simple mechanical lock consisting of a metal rod that slides into a metal sleeve (the barrel) and then into a catch plate on the door frame to secure a door or gate. Its purpose is to provide a basic level of security and privacy, allowing users to lock doors from a single side for added reinforcement or to prevent accidental openings. Barrel bolts are a cost-effective and easy-to-install option, suitable for various applications like sheds, closets, bathroom doors, and even for securing interior or exterior gates.
