A barrel bolt is a simple locking mechanism used to secure doors, gates, cabinets, or windows from one side. Also known as a sliding bolt lock or shoot bolt, it consists of two main parts: a metal bar that slides and a plate that holds it in place. These bolts are surface-mounted, with the bolt sliding into a catch on the other side of the door. They’re particularly suitable for single-leaf doors and the passive leaf of double doors. Whether you’re adding privacy to a bedroom or updating a bathroom lock, barrel bolts offer a sleek, easy-to-install solution. You can choose from various styles and finishes to match your home or commercial application.
