Latches and locks are two common mechanisms to secure doors, gates, cabinets, and other objects. Both latches and locks serve the same purpose: to prevent unauthorized access to the object being secured. However, they differ in terms of their operation and level of security. This article will explore the differences between latches and locks, how they work, and their various types.
Latches:
A latch is a simple mechanism that keeps a door or gate closed. It operates using a lever or bolt that slides into a slot or catches. Latches are commonly used in residential settings and are less secure than locks. There are various latches, including spring, slam, cabin hooks, and gate latches.
Spring latches are the most common type of latch used in many household doors. They have a spring-loaded bolt that snaps into a catch when the door is closed. On the other hand, slam latches are commonly used in industrial settings and have a spring-loaded bolt that engages when the door is slammed shut. Cabin hooks secure cabin doors and have a sliding hook that engages into a catch. Gate latches secure gates and has a sliding bolt that engages into a catch.
Locks:
Locks are more secure than latches and are commonly used in commercial settings. They use a key or combination to release a bolt or lever that closes the door. There are various locks, including padlocks, deadbolts, mortise, and cam locks.
Padlocks are portable locks that secure sheds, gates, and lockers. They have a shackle that can be locked into a clasp using a key or combination. Deadbolts are commonly used in residential settings and are mounted on the door frame. They have a bolt that extends into the door jamb when locked. Mortise locks are commonly used in commercial settings and are mounted inside the door. They have a mortise lock body installed in a pocket in the door and a cylinder inserted into the lock body. Cam locks are commonly used in cabinets with a rotating cam that engages with a latch or catches when the key is turned.
