The difference between a double-opening handle lock and a single-opening handle lock lies in the unlocking method and safety.
Unlocking method:
A single-opening handle lock has a keyhole on the outside, which requires a key to unlock outdoors. There is a knob inside, which does not require a key to unlock indoors. You can unlock it by turning the knob.
A double-opening handle lock has keyholes both indoors and outdoors, and you must use a key to unlock it.
Safety:
The single-opening handle lock has a stronger escape function, because in case of an emergency such as a fire, you can quickly open the door without finding a key.
The double-opening handle lock has a weaker escape function, because in an emergency, you need to find a key to open the door, which poses a safety hazard12.
In summary, the main difference between a single-opening handle lock and a double-opening handle lock lies in the unlocking method and safety. Users can choose the appropriate type of handle lock according to their needs and safety considerations.
The difference between single-open and double-open handle locks
1. Single-open handle lock
A single-open handle lock has a keyhole on the outside, and a key is required to open the lock outdoors. There is a knob inside, and no key is required indoors. You can open the lock by turning the knob. This lock has a strong escape function.
2. Double-open handle lock
A double-open handle lock has keyholes indoors and outdoors, and you must use a key to open the lock. The escape function of a double-open handle lock is relatively weak, because in the event of a fire, you have to find a key to open the door, which is a big safety hazard. If it is a single-open handle lock, you can open the door by turning the knob.
