Latch locks are one of the most commonly used door locking mechanisms, valued for their simplicity, reliability, and versatility in both residential and commercial settings. Designed to keep doors securely closed while allowing easy access, latch locks function through a spring-loaded latch that retracts when a handle or knob is turned. These locks are widely used on internal doors, entryways, and even light-duty exterior applications where convenience and basic security are essential. With various designs available, latch locks provide an effective balance between accessibility and protection, making them an important component in modern door hardware systems.
What Are Latch Locks?
Latch locks are mechanical devices that secure doors using a latch bolt, which fits into a strike plate installed on the door frame. When the door closes, the latch automatically engages, keeping the door shut without requiring a key. The latch retracts when the handle, lever, or knob is operated, allowing the door to open smoothly.

Tubular Latch Locks
Widely used in modern door hardware, tubular latch locks are compact and easy to install, making them suitable for residential use.
Rim Latch Locks
Mounted on the surface of the door, rim latch locks are commonly found in traditional settings and work well with rim door knobs.
