Fingerprint door lock with a heavenly hook

To be honest, I don't know when Xiaobian has not been exposed to the smart lock industry until it is not a smart lock industry. Some security doors are taking the heaven and earth hooks. Some will not take a heaven and earth hook.
 
The heavens hook, as the name implies are the sides of the security door, and the hooks on the lower part.
 
I believe that many owners are also the same as Xiaobian, pay attention to the heavens hooks to change the ordinary mechanical locks in the family, because you buy a fingerprint door lock, business is generally confirmed to confirm whether your home security door is to bring Heavenly hook.
 

At present, there are still many brand fingerprint door locks that are not suitable for the security door of the world, especially those who have some owners' homes are Wang Li locks. Some special locks, such as the world, the hook adapter is a very headache. Things, many locksmith also have feedback to the way to install fingerprint door locks, many owners do not agree, the owners are worried that they are not safe, and the locksmen think that the heavens hook is excessive, everyone hooks Cognition is different, causing the debate.
