deadbolt 🔊
Meaning of deadbolt
A type of locking mechanism that slides into a metal bracket to securely lock a door, often requiring a key or thumb turn to operate.
Key Difference
A deadbolt is distinct from other locks due to its solid metal bolt that extends deeply into the door frame, providing enhanced security compared to spring-latch locks.
Example of deadbolt
- After the recent burglary in the neighborhood, John installed a heavy-duty deadbolt on his front door for added security.
- The old mansion's doors were fitted with antique brass deadbolts, making them nearly impossible to pick.
Synonyms
latch 🔊
Meaning of latch
A fastening device that holds a door closed, typically operated by a spring mechanism.
Key Difference
Unlike a deadbolt, a latch does not require manual locking and is less secure as it can be easily forced open.
Example of latch
- The screen door clicked shut with a light latch, but it wouldn’t stop an intruder.
- She lifted the latch quietly, trying not to wake anyone as she slipped inside.
padlock 🔊
Meaning of padlock
A detachable lock with a hinged or sliding shackle, often used for gates, lockers, or chains.
Key Difference
A padlock is portable and not built into the door like a deadbolt, making it versatile but less integrated for home security.
Example of padlock
- He secured the storage unit with a heavy-duty padlock to protect his belongings.
- The bicycle was left outside, fastened to the rack with a small padlock.
mortise lock 🔊
Meaning of mortise lock
A lock recessed into the edge of a door, offering high security due to its complex mechanism.
Key Difference
Mortise locks are more intricate and require a pocket (mortise) in the door, whereas deadbolts are surface-mounted or drilled in.
Example of mortise lock
- The historic bank vault door was fitted with a brass mortise lock, a relic of early 20th-century security.
- Modern office buildings often use mortise locks for their durability and sleek appearance.
cylinder lock 🔊
Meaning of cylinder lock
A lock mechanism where the key rotates a cylinder to retract the bolt.
Key Difference
Cylinder locks are often part of a deadbolt system but refer specifically to the key-operated component rather than the entire locking mechanism.
Example of cylinder lock
- The locksmith replaced the old cylinder lock to improve the apartment’s security.
- High-security cylinder locks are resistant to picking and bumping.
barrel bolt 🔊
Meaning of barrel bolt
A simple sliding bolt used to fasten doors or gates, often manually operated.
Key Difference
A barrel bolt lacks the key-operated mechanism of a deadbolt and is usually used for secondary security.
Example of barrel bolt
- She slid the barrel bolt across the barn door to keep the animals from escaping.
- The garden gate had a rusty barrel bolt that squeaked when moved.
rim lock 🔊
Meaning of rim lock
A surface-mounted lock often found on older doors, featuring a decorative plate.
Key Difference
Rim locks are mounted on the door's surface rather than inside it, unlike deadbolts which are more concealed.
Example of rim lock
- The antique rim lock on the Victorian-era door was more decorative than functional.
- Restorers carefully preserved the original rim locks when renovating the heritage house.
night latch 🔊
Meaning of night latch
A lock that automatically engages when the door is closed but can be opened from the inside without a key.
Key Difference
A night latch is spring-loaded and less secure than a deadbolt, which requires manual or key operation.
Example of night latch
- The night latch provided convenience but wasn’t enough to deter break-ins.
- He forgot his keys, but thankfully the night latch allowed him to open the door from the inside.
keyless lock 🔊
Meaning of keyless lock
A lock that uses electronic or biometric mechanisms instead of a traditional key.
Key Difference
Keyless locks rely on digital access, whereas deadbolts are mechanical and key-operated unless they are smart deadbolts.
Example of keyless lock
- The new smart home had a keyless lock that opened with a fingerprint scan.
- Many hotels now use keyless locks for guest room security.
hasp 🔊
Meaning of hasp
A metal fastening with a hinged slotted part that fits over a staple and is secured by a padlock.
Key Difference
A hasp is an external fastener requiring a padlock, unlike a deadbolt which is an integrated locking mechanism.
Example of hasp
- The shed door was secured with a hasp and a sturdy padlock.
- Campers often use a hasp to lock their food containers against wildlife.
